Exosomes are extracellular vesicles (that’s particles that release naturally from a cell that cannot replicate) that are responsible for certain genetic information, otherwise known as Exosomes cell to cell communication. They transport molecules that are essential regulators of intracellular information between close and distant cells.
Exosomes play a vital role in the communication and rejuvenation of all the cells in our body. Despite not being a cell, Exosome has proven to be quite important in maintaining a healthy cellular terrain.
Exosomes are typically made by growing stem cells in culture. Taking the media where they grow and then getting rid of the stem cells. Due to the small size of Exosomes, the media is then ultra-centrifuged to concentrate the exosomes.
Exosomes contain different molecular constituents of their cell origin; these include proteins and RNA. Meanwhile, the Exosomal proteins composition varies with the cell and tissue of the origin; most Exsomes contains an evolutionarily conserved common set of protein molecules.
HOW TO ISOLATE EXOSOME FROM CULTURE STEM?
Exosomes can be isolated from culture stem cell using the method Ultracentrifugation. Often combined with sucrose density gradients, they float the relatively low-density Exosomes from other microvesicles. Cells and larger particles are removed by sequentially increasing the centrifugal forces. These procedures can take up to 30hours and requires an ultracentrifuge, extensive training and specialized equipment.
This method provides highly enriched exosomes but requires specialized training and equipment.
Now, this is how Exosomes works:
Exosomes carry genetic information. Protein and messenger RNA, they can relay this information, letting cells know when to and how to react. This Exosomes cell-to-cell communication is possible due to its unique shape and content.
Exosomes from young stem cells rejuvenate the older cells and assist in calming an overreactive immune system or modulating it to respond in a coordinated and more effective fashion.
WHAT IS EXOSOME THERAPY?
Exosome therapy is one of the hottest areas of regenerative medicine treatment. Researchers have given us valuable insight into the practical functionality of exosomes. While stem cells are usually responsible for the rejuvenation of older cells, they may not be able to supply all the information needed. So supporting Exosome function could have a greater positive effect, by providing a new piece of information to enhance the healing process.
Exosome therapy is a minimally invasive procedure commonly used in orthopedic injuries, for anti-aging and some other degenerative diseases. Exosomes treatment contains growth factors, messenger RNA, micro RNA, cytokines and other biologically active molecules in conjunction with stem cell therapy to speed up healing benefit.
Exosome therapy can be injected into the affected area like in orthopedic injuries or given intravenously for anti-aging.
This Exosome injection is administered directly into the affected area, and the dosing for every patient varies, and there is no set protocol.
Exosomes treatment is gaining popularity recently, due to its ability to transfer molecules from one cell to another via membrane vesicle, therefore influencing the immune system, such as dendrite cells and B cells.
What is exosome therapy used for?
HAIR LOSS: Exosomes injection can be used to regrow hair loss due to its growth factor content. When injected, Exosome will trigger healing, cell stimulation and natural regeneration of these hair follicles. Exosome hair loss therapy is cutting-edge in hair restoration. According to research, there is a positive relationship between Exosomes and Hair loss. Exosomes are ideal for people with thinning hair, excessive shedding or hair loss proper. This is because Exosomes are regenerative cells that can heal, repair, stimulate and restore cells and tissues.
LYME DISEASE: Exosomes may help to regulate processes in the body, and may also be beneficial to patients with Lyme disease. Lyme disease is a very complex disease, which compromises the immune system. Many Lyme patients suffer from dysfunction of the mast cells, increasing their inflammatory response and metabolic function. Incorporating Exosomes treatment in their treatment regimen may help break the inflammatory response and provide the body with necessary cellular information to facilitate healing.
ARTHRITIS: Arthritis as we all know, is the joint inflammation resulting from an autoimmune disease. Although various types of treatment are available to alleviate symptoms, no known therapy has been confirmed effective in reversing the disease progression.
In the field of regenerative medicine today, with the discovery of extracellular microvesicles, especially exosomes, many researchers have been able to offer a more exciting alternative on this subject matter. Exosome arthritis therapy is believed to play a more substantial role in bone and cartilage remodeling.
In a nutshell, Exosomes provides enormous potential in the field of regenerative medicine. You can advance your understanding of Exosomes and its relationship with stem cell in this course. This is an online-course https://www.cellulartherapycourse.com/ where physicians and medical personnel can get insight and deep understanding of this novel science (Exosome).
The human immune system helps to protect the body against illness and infection caused by bacteria, viruses, fungi, and parasites. This process is achieved by a collection of reactions and responses made by the body to damage these infected cells. It is also called immune responses.
This immune system is very crucial in cancer patients to help fight cancer, it dictates this cancer as abnormal and destroys it, but this is not enough to rid of cancer altogether. In most cases, cancer will weaken this immune system because it will spread into the bone marrow that produces blood cells that fights against infections and cause the bone marrow to decrease in its blood cell production.
When this immune system is unable to recognize these cells as abnormal, cellular growth will occur, causing uncontrolled growth and division of cells, that will, in turn, lead to cancer.
Cancer has been a serious and sensitive talk for both patients and doctors. Being diagnosed with cancer is frightening and tormenting, but due to the latest treatment method, recovering from this disease is increasingly possible. Living with cancer often brings an initial psychological crisis, but surprisingly it does not only affect you but your family and others close to you.
Cancers, especially genetic cancer can’t be prevented, so it is essential to be proactive about your health. If you’re diagnosed with cancer, some individual lifestyles that will help improve your cancer care, which includes managing stress. Reducing your stress level can help you to maintain physical and mental stress; you can use relaxation techniques such as meditation and yoga. Getting enough sleep is also crucial for patients living with cancer; this will help improve their health, mood, and coping ability. Also, it is best the limit their exposure to toxins that can increase one’s risk of being exposed to other deadly diseases.
A healthy feeding habit is critically important and can help manage cancer side effects, improve health, and quick recovery. Some tips to help you develop a good and healthy feeding diet include:
- Consuming assorted types of vegetables in all your meals. Vegetables are essential and should not just be a side dish but the centerpiece of your meal.
- Consuming foods rich in fiber like grains, beans, peas, nuts, and seeds.
- Consuming less red meat, like pork, lamb, goat, and bison.
- The presence of probiotic and prebiotic foods helps to support a healthy gut. Probiotic foods include yogurt or other fermented vegetables, and prebiotic foods include raw or cooked onions, dandelion greens, and legumes.
- Avoid processed and canned foods
- Avoid foods high in calories and low in nutrients like fruit-flavored drinks, sodas, candies, and sweets.
- Lastly, cut down on the excessive intake of alcohol.
Some other routines can help improve cancer care like regular exercise. Regular exercise helps to control fatigue, muscle tension, and anxiety in those with cancer, and it is essential, especially during and after cancer treatment, so keep fit and avoid adding unnecessary weight.
There are many cancer treatment options for different types of cancers. Cancer treatments depend on the type and how to advance it is. Some patients with cancer will only have one treatment option, while others will end up with a combination of more that one treatments technique depending on the type and stage of cancer.
Curing cancer is one of the significant challenges of the 21st century. However, few advances to tame the immune system are getting closer to a future where cancer can be a curable disease.
Although cancer treatment is dependent on the stage and type, we need a wide range of therapies that work on cellular level like NK cell and stem cell therapies, wide enough to cover the whole spectrum of cancer. Cancer therapies involving the immune system is believed to be a milestone for cancer treatment advances, and the development of multiple immune cells as a therapeutic tool.
Our knowledge of cancer has dramatically improved in recent years. And it seems increasingly evident that there has been a surge of new technologies, and these technologies could make a great impact on the way we treat cancer, taking us closer to finally curing this deadly disease.
One of these promising cancer treatment advances is the natural killer (NK) cell-based immunotherapy.
Natural killer cells have emerged as the newest promising therapeutic approach to cancer. Our understanding of the biological processes that take place in cancer is increasing rapidly, leading to this new type of targeted treatment and therapeutic approach. It is hard to overstate the possible importance of NK cells in the future of cancer. Modern researches have shown that NK cells are a type of treatment that stimulates a persons’ immune system to fight cancer, and this may give room for a greater number of chances to beat cancer for good. NK cells are also known for their ability to target cancer stem cells making these cancer stem cells visible to the immune system.
NK cells was first identified in the 1970s as a unique lymphocyte subset that can recognize and kill abnormal cells without prior sensitization of specific tumor antigen, thus preventing the growth of many cancers. During the late 1980s, something was observed, and this was that NK cells could destroy a lymphoma cell line that had lost MHC class I surface molecules while the original MHC class I+ cells were resistant to lysis, which led to the formation of the “missing self-hypothesis” which states that NK cells can sense the absence of “self” MHC class-I molecule on target cells. In recent years, the hypothesis was confirmed by the inhibitory and activating NK cell receptors.
This discovery indicates that autologous cells are not killed by NK cells, thanks to an appropriate expression of all self-HLA alleles, do not kill an autologous cell. In contrast, a wide spec of cancer types can be killed due to the loss of HLA molecules and to the expression/overexpression of ligands for NK cell activating receptors.
Now, this is how NK therapy works
NK cells firsts recognize the tumor cells via stress or danger signals from their sensors.
Then, the Activated NK cells directly decimate the target tumor cells through at least four mechanisms. These mechanisms are cytoplasmic granule release, death receptor-induced apoptosis, effector molecule production, or ADCC.
Furthermore, NK cells act as regulatory cells when reciprocally interact with DCs to improve their antigen uptake and presentation. This action helps in facilitating the generation of antigen-specific CTL responses that is vital in dictating foreign invasion and tumor cells.
Also, by producing cytokines such as IFN-γ, activated NK cells induce CD8+ T cells to become CTLs. Activated NK cells can also help in the differentiation of CD4+ T cells toward a Th1 response and promote CTL differentiation. Cytokines produced by NK cells might even have the unique ability to regulate antitumor cells, making them more proactive.
Accordingly, The cytokine gene transfer approach induces NK cell proliferation, and this increases survival capacity. Further enhancing their activation and also making them more potent in malignant cell multiplication dictation.
The NK cell scientist has assured that by using NK cell lines, modifying genes such as IL-2, IL-12, IL-15, and stem cell factor (SCF). They have been demonstrated the ability of the NK to restore their cytotoxic capacity as well as increase their proliferative rate, survival ability, and in vivo antitumor activity. However, the specificity of NK cells is still limited, and studies are even passing through phases. The approach focuses on retargeting NK cells to tumor cells by gene transfer of chimeric tumor-antigen specific receptors.
NK therapy is promising research; it raises the prospect of “one-end-solution” to many different types of cancers across the Globe. If the studies and experiments work out pretty well, the NK cells will be able to increase the activity of CD4+, CD19, and other important disease-fighting cells of the body.
There is no doubt that this an unimaginable feat, both in advancing our basic knowledge about regenerative medicine and for the possibility of future cancer treatment advances.
Some people believe that stem cell does all of this but studies have shown that It’s unlikely only in a few unique cases. You can observe minimal growth a year after the patient took treatment, but this doesn’t mean replacement of the cartilage.
The cartilage has a reduced regenerative capacity, and current and present pharmacological medications only offer symptomatic pain relief. Osteoarthritis patients that respond poorly to conventional therapies are ultimately treated with surgical procedures to promote cartilage repair by implantation of artificial joint structures (arthroplasty) or total joint replacement (TJR). Surgery has been the last resort for serious cartilage problems.
In the last two decades, stem cells derived from various tissues with varying differentiation and tissue regeneration potential have been used for the treatment of osteoarthritis, damage to bones and others either alone or in combination with natural or synthetic scaffolds. The stem cells derived from these tissues primarily aid cartilage repair. Although stem cells can be differentiated into chondrocytes in vitro or aid cartilage regeneration in vivo, their potential for Osteoarthritis management remains limited as cartilage regenerated by stem cells fails to fully recapitulate the structural and biomechanical properties of the native tissue. It isn’t easy for the cartilage to regrow and assume its original biomechanical and structure form.
Apparently, Due to the limited intrinsic capacity of resident chondrocytes to regrow the lost cartilage post-injury, stem cell-based therapies have been proposed as a novel therapeutic approach for cartilage repair.
Also, stem cell-based therapies using mesenchyme stem cells (MSCs) or induced pluripotent stem cells (iPSCs) have been used successfully in clinical and preclinical situations.
Part of the issues associated with Mesenchyme stem cells can be averted by using iPSCs. iPSCs are an ideal patient-specific unlimited cell source for autologous tissue regeneration. With the Promising in vitro; studies have shown that vitro results have already been demonstrated in the cartilage engineering field for iPSCs. These were generated from various cell types.
What Is Cartilage and How Does It Get Damaged?
Cartilage is a connective tissue in the human body and body of other animals. In our joints, we have a few kinds of cartilage, but most often people refer to the smooth lining of a joint called articular or hyaline cartilage. This kind of cartilage gives rise to a soft layer of cushion on the end of a bone at the joint. The cushion is essential for balance, mechanical functions and athletics. This tissue of the cartilage is very strong, yet it can compress, readjust and absorb varying degrees of energy. It is also very slippery, smooth and flexible and these features allow the joint to glide effortlessly through a broad range of physical motions of any kind.
When joint cartilage is not working correctly or damaged, this smooth-cushioning-layer can be worn away, and this becomes a problem. In the case of traumatic injuries, sometimes a sudden force causes the cartilage to break off or poorly become damaged, exposing the underlying bone of the body. In the case of osteoarthritis (also called degenerative/wear-and-tear arthritis), over time that smooth layer can wear thin and uneven. Aging can also cause the cartilage to break off and certain life factors and diseases too, e.g. autoimmune diseases.
Eventually, as that cushion of the bones wears away, joint movements can become inflexible, stiff and painful on one or both legs (bones). Joints can even become inflamed and swollen. And as all these conditions, typically causes pain and limitations in activity become problematic. The action or activities that involve these bones leads to crushing pain and discomfort, depending on the severity of the case. Almost all activities involve the movement of bones; hence this condition is not an easy one.
There are some treatments for cartilage damage and arthritis. Although there some medicines, most of these treatments are focused either on relieving symptoms by smoothing down the damaged cartilage or concentrate on replacing the joint surface with an artificial implant. The later is for end-stage conditions, and the artificial plane is procedures such as knee replacement or hip replacement surgery.
How Can Stem Cells Help?
Stem cells are specialized cells that can multiply reform and develop into different types of tissue. In the developmental stages of a fetus, stem cells are plentiful and surplus. However, in adulthood, stem cells are restricted to specific tasks of regenerating a few types of cells, such as blood cells and liver cells in some cases of damage. There are almost no stem cells found in cartilage tissue, and therefore there is little to no capacity to heal or regrow new cartilage. For adults, the ability to regrow new cartilage is even more difficult due to age and lack of stem cells in the cartilages.
Most often, in the setting of orthopedic surgery and joint problems, stem cells are obtained from adult stem cell sources. The primary sources are bone marrow and fatty tissue. These stem cells can develop into cartilage cells, called chondrocytes.
They also exhibit some other helpful qualities by stimulating the body to reduce inflammation, stimulate cell repair, and improve blood flow. This process is caused by the secretion of cellular signals and growth factors to stimulate the body to initiate healing processes.
Once stem cells have been obtained, they need to be delivered to the area of the cartilage that damaged. One option is to inject the stem cells into the joint. There have been many studies investigating just this, and some data shows improvement in symptoms. How much of this improvement is the result of new cartilage growth versus other effects of stem cells (the healing properties listed above, including the anti-inflammatory effects) is unknown.
There is a challenge with giving stem cell injection. The problem with just injecting stem cells is that cartilage is a complex tissue that is comprised of more than only cells hence this can pose a challenge because the stem can’t regenerate all the things in the cartilage.
To regrow the cartilage, the complex tissue structure and biomechanics of cartilage must also be reconstructed to its former status. Cartilage can often /described as having a scaffold-like structure that is composed of water, cells, collagen, and proteoglycans, and infection-fighting antibodies. Injecting just the stem cells is thought to be less effective in stimulating the formation of the entire cartilage structure hence the challenge.
Some studies are investigating the types of 3-dimensional tissue scaffolds engineered to have a cartilage-like structure. The stem can then be injected into the scaffold, in hopes of better restoring a healthy type of cartilage. Three-dimensional printing is becoming an exciting part of this type of research. If everything works out as expected, the cartilage reconstruction could be achieved to a very high percentage.
How do stem cells work?
Necessarily, stem cells are progenitor cells which are capable of regeneration and differentiation into a wide range of specialized cell types. Once injected, stem cells follow inflammatory signals from damaged tissues and have multiple ways of repairing these damaged areas. It works as though the part is developing new; like what is seen during a child’s development.
The mesenchyme stem cells (MSCs) we are using are considered to be multipotent (they can transform into different cell types but cannot form an organ) but not pluripotent. In the body, these cells Do NOT function by transforming into different cell types or tissues.
They act via anti-inflammatory activity, immune modulating capacity, and the ability to stimulate regeneration. We go through a very high thorough screening process to find cells that we know have the best anti-inflammatory activity, the best immune modulating capacity, and the best ability to stimulate regeneration process on the tissue with damage.

The ISSCA provides certifications and standards in the practice of Regenerative Medicine as a medical specialty.
Although the expectation on this stem cell course is yet to be achieved; however, this is a part of medicine that can offer one-end-solution to various bone and body problems.
With the recent high-tech studies, efforts and dynamics, stem cell treatment can be a breakthrough in the future as its perspectives are very promising and unique. It is also not dangerous on the long-run.
Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell. Pluripotent stem cells hold promise in the field of regenerative medicine. Because they can propagate indefinitely, as well as give rise to every other cell type in the body (such as neurons, heart, pancreatic, and liver cells), they represent a single source of cells that could be used to replace those lost to damage or disease.
Natural killer cells are the type of cytotoxic lymphocyte critical to the innate immune system. The role NK cells play is analogous to that of cytotoxic T cells in the vertebrate adaptive immune response. NK cells provide rapid responses to virus-infected cells, acting at around three days after infection, and respond to tumor formation.
Typically, immune cells detect the major histocompatibility complex (MHC) presented on infected cell surfaces, triggering cytokine release, causing apoptosis. NK cells are unique, however, as they can recognize stressed cells in the absence of antibodies and MHC, allowing for a much faster immune reaction.
Clinical Trial on NK cells
In a first clinical trial, a natural killer cell immunotherapy derived from induced pluripotent stem cells is being tested for safety in 64 patients with a variety of solid tumors. The first subjects used for the study received the cells in February at the University of California, San Diego (UCSD) Moores Cancer Center and MD Anderson Cancer Center.
This study is targeting late-stage cancer patients with solid tumors, including lymphoma, colorectal cancer, and breast cancer. The FT500 NK cells do not undergo any further alterations and after their derivation from the induced pluripotent stem cells (iPSCs), offering the possibility of a quicker, ready-made treatment.
Human embryonic stem cells induced iPSCs
Human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) provide an accessible, genetically tractable, and homogenous starting cell population to efficiently study human blood cell development. These cell populations provide platforms to develop new cell-based therapies to treat both malignant and nonmalignant hematological diseases.
The NK cells are immune cells in the same family as T and B cells and are very good at targeting cancer cells for destruction. Some Laboratory experiments have shown they do so by attacking cells that have lost their significant self-recognition signals that tell the immune system not to attack. This is the phenomenon that can happen among cancer cells but not to healthy cells. Experts are not sure how many cancer cells lose that signal. Researchers are hopeful that the clinical trial can help determine which cancer patients could benefit the most from NK cell treatment.
The ability to induce pluripotent stem cells from committed, human somatic cells provides tremendous potential for regenerative medicine. However, there is a defined neoplastic potential inherent to such reprogramming that must be understood and may offer a model for critical understanding events in the formation of the tumor. Using genome-wide assays, we identify cancer-related epigenetic abnormalities that arise early during reprogramming and persist in induced pluripotent stem cell (iPS) clones. These include hundreds of abnormal gene silencing events, patterns of aberrant responses to epigenetic-modifying drugs resembling those for cancer cells, and presence in iPS and partially reprogrammed cells of cancer-specific gene promoter DNA methylation alterations.
Progress in adoptive T-cell therapy for cancer and infectious diseases is hampered by the lack of readily available antigen-specific, human T lymphocytes. Pluripotent stem cells could provide an estimable source of T lymphocytes, but the therapeutic potential of human pluripotent stem cell-derived lymphoid cells generated to date remains uncertain.
Modification of T cells
Recently, some Approved cell therapies for Cancer also rely on modifying T cells, in those cases to produce cancer cell–binding chimeric antigen receptors (CARs), and have been effective in treating certain cancers such as leukemia.
Application of CAR T-Cell Therapy in Solid tumours
The Car T technology has wowed the field by all but obliterating some patients’ blood cancers, but solid malignancies present new challenges.
Therapies that contains such chimeric antigen receptor (CAR) T cells have been approved for some types of so-called liquid cancers of the blood and bone marrow, large B-cell lymphoma and B-cell acute lymphoblastic leukemia. But the approach has not had as much success for solid tumors.
Serious research into the therapy for brain cancer started almost 20 years ago after cancer biologist WaldemarDebinski, then at Penn State, discovered that the receptor for the immune signaling molecule interleukin 13 (IL-13) was present on glioblastomas, but not on healthy brain tissue. The receptor thus seemed like an excellent target to home in on cancer cells while sparing healthy ones. The CAR spacer domain that spans the immune cells’ membranes and its intracellular co-stimulatory areas, as well as the process used to expand cells outside the body, to boost the T cells’ activity.
CAR T- A Safer Cell Therapy
While managing CAR T-cell therapy toxicity could help keep already-designed treatments on their march to the clinic, many immunotherapy companies are also working to develop a new generation of inherently safer therapies, yet just as efficient. A crucial part of achieving this goal will be improving CAR specificity for target cells. With current treatments, the destruction of normal cells is often an unavoidable side effect when healthy tissue carries the same antigens as tumors; noncancerous B cells, for example, are usually casualties in CD19-targeted therapies.
CAR T delivery is a non-easy factor in the treatment of solid tumors and other unknown forms of tumors. With the non-solid cancers, cells are administered by a blood infusion, and once in circulation, the CAR T can seek out and destroy the rogue cells. For solid tumors, it’s not so simple.
The main drawback of taking cells from a patient and developing them into a cellular immunotherapy product is that the process can take weeks.
Patel tells The Scientist “But for the majority of patients who may not be a candidate or may not have time to wait for such an approach, the idea that there’s off-the-shelf immunotherapy that could potentially as a living drug act against their cancer, I think is a fascinating concept,”
Insulin-producing cells grown in the lab could provide a possible cure for the age-long disease (diabetes).
Type 1 diabetes is an auto¬immune disease that wipes out insulin-producing pancreatic beta cells from the body and raises blood glucose to dangerously high levels. These high levels of Blood sugar level can be even fatal. Patients are being administered insulin and given other medications to maintain blood sugar level. To those who cannot maintain their blood sugar level, they are given beta-cell transplants but to tolerate beta cell transplants; patients have to take immunosuppressive drugs as well.
A report by a research group at Harvard University tells us that they used insulin-producing cells derived from human embryonic stem cells (ESCs) and induced pluripotent stem cells to lower blood glucose levels in mice. Nowadays, many laboratories are getting rapid progress in human stem cell technology to develop those cells that are functionally equivalent to beta-cells and the other pancreatic cell types. Other groups are developing novel biomaterials to encapsulate such cells and protect them against the immune system without the need for immunosuppressant.
Major pharmaceutical companies and life sciences venture capital firms have invested more than $100 million in each of the three most prominent biotechnological industries to bring such treatments into clinical use:
- Massachusetts–based companies Semma Therapeutics
- Sigilon Therapeutics, and ViaCyte of San Diego
Researchers of UC San Francisco have transformed human stem cells into mature insulin-producing cells for the first time, a breakthrough in the effort to develop a cure for type-1 (T1) Diabetes. Replacing these cells, which are lost in patients with T1 diabetes, has long been a dream of regenerative medicine, but until now scientists had not been able to find out how to produce cells in a lab dish that work as they do in healthy adults.
What is T1 diabetes?
T1 diabetes is an autoimmune disorder that destroys the insulin-producing beta cells of the pancreas, typically in childhood. Without insulin’s ability to regulate glucose levels in the blood, spikes in blood sugar can cause severe organ damage and eventually death. The condition can be managed by taking regular shots of insulin with meals. However, people with type 1 diabetes still often experience serious health consequences like kidney failure, heart disease and stroke. Patients facing life-threatening complications of their condition may be eligible for a pancreas transplant from a deceased donor, but these are rare, and they are supposed to wait a long time.
Researchers have just made a breakthrough that might one day make these technologies obsolete, by transforming human stem cells into functional insulin-producing cells (also known as beta cells) – at least in mice.
“We can now generate insulin-producing cells that look and act a lot like the pancreatic beta cells you and I have in our bodies,” explains one of the team, Matthias Hebrok from the University of California San Francisco (UCSF).
“This is a critical step towards our goal of creating cells that could be transplanted into patients with diabetes.”
Type-1 diabetes is characterized by a loss of insulin due to the immune system destroying cells in the pancreas – hence, type 1 diabetics need to introduce their insulin manually. Although this is a pretty good system, it’s not perfect.
Making insulin-producing cells from stem cells
Diabetes can be cured through an entire pancreas transplant or the transplantation of donor cells that produce insulin, but both of these options are limited because they rely on deceased donors. Scientists had already succeeded in turning stem cells into beta cells, but those cells remained stuck at an early stage in their maturity. That meant they weren’t responsive to blood glucose and weren’t able to secrete insulin in the right way.
Scientists at the University of California San Francisco made a breakthrough in the effort to cure diabetes mellitus type 1.
For the first time, researchers transformed human stem cells into mature insulin-producing cells, which could replace those lost in patients with the autoimmune. There is currently no known way to prevent type-1 (T1) diabetes, which destroys insulin production in the pancreas, limits glucose regulation, and results in high blood sugar levels. The condition can be managed with regular shots of insulin, but people with the disease often experience serious health complications like kidney failure, heart disease, and stroke.
“We can now generate insulin-producing cells that look and act a lot like the pancreatic beta cells you and I have in our bodies,” according to Matthias Hebrok, senior author of a study published last week in the journal Nature Cell Biology.
“This is a critical step toward our goal of creating cells that could be transplanted into patients with diabetes,” Hebrok, director of the UCSF Diabetes Center, said in a statement.
Islets of Langerhans are groupings of cells that contain healthy beta cells, among others. As beta cells develop, they have to separate physically from the pancreas to form these islets.
The team artificially separated the pancreatic stem cells and regrouped them into these islet clusters. When they did this, the cells matured rapidly and become responsive to blood sugar. In fact, the islet clusters developed in ways “never before seen” in a lab. After producing these mature cells, the team transplanted them into mice. Within days, the cells were producing insulin similar to the islets in the mice. While the study has been successful in mice, it still needs to go through more rigorous testing to see if it would work for humans as well. But the research is up-and-coming. “We can now generate insulin-producing cells that look and act a lot like the pancreatic beta cells you and I have in our bodies. This is a critical step towards our goal of creating cells that could be transplanted into patients with diabetes,” He said.
“We’re finally able to move forward on several different fronts that were previously closed to us,” he added. “The possibilities seem endless.”
Basic research keeps elucidating new aspects of beta cells; there seem to be several subtypes, so the gold standard for duplicating the cells is not entirely clear. Today, however, there is “a handful of groups in the world that can generate a cell that looks like a beta cell,” says Hebrok, who currently acts as scientific advisor to Semma and Sigilon, and has previously advised ViaCyte. “Certainly, companies have convinced themselves that what they have achieved is good enough to go into patients.”
The stem cell reprogramming methods that the three companies use to prompt cell differentiation create a mixture of islet cells. Beta cells sit in pancreatic islets of Langerhans alongside other types of endocrine cells. Alpha cells, for example, churn out glucagon, a hormone that stimulates the conversion of glycogen into glucose in the liver and raises blood sugar. Although the companies agree on the positive potential of islet cell mixtures, they take different approaches to developing and differentiating their cells. Semma, which was launched in 2014 to commercialize the Harvard group’s work and counts Novartis among its backers, describes its cells as fully mature, meaning that they are wholly differentiated into beta or other cells before transplantation. “Our cells are virtually indistinguishable from the ones you would isolate from donors,” says Semma chief executive officer BastianoSanna
To get around the donor problem, researchers, including the team at UCSF has been working on nudging stem cells into becoming fully-functional pancreatic beta cells for the last few years. Still, there have been some issues in getting them all the way there.
“The cells we and others were producing were getting stuck at an immature stage where they weren’t able to respond adequately to blood glucose and secrete insulin properly,” Hebrok said.
“It has been a major bottleneck for the field.”
“We’re finally able to move forward on a number of different fronts that were previously closed to us,” Hebrok added. “The possibilities seem endless.”
Regardless of starting cell type, the companies say they are ready to churn out their cells in large numbers. Semma, for example, can make more islet cells in a month than can be isolated from donors in a year in the United States, Sanna says, and the company’s “pristine” cells should perform better than donor islets, which are battered by the aggressive techniques required for their isolation.
As these products, some of which have already entered clinical trials, move toward commercialization, regulatory agencies such as the US Food and Drug Administration (FDA) and the European Medicines Agency have expressed concern about the plasticity of the reprogrammed cells. All three firms subject their cells to rigorous safety testing to ensure that they don’t turn tumorigenic. Before successful trials, companies won’t know the dose of beta cells required for a functional cure, or how long such “cures” will last before needing to be boosted. There’ll be commercial challenges, too: while the companies are investing heavily to develop suitable industrial processes, all acknowledge that no organization has yet manufactured cell therapies in commercial volumes.
Nevertheless, there’s growing confidence throughout the field that these problems will be solved, and soon. “We have the islet cells now,” says Alice Tomei, a biomedical engineer at the University of Miami who directs DRI’s Islet Immuno-engineering Laboratory.
“These stem cell companies are working hard to try to get FDA clearance on the cells.”
Protecting stem cell therapies from the immune system
Whatever the type of cell being used, another major challenge is delivering cells to the patient in a package that guards against immune attack while keeping cells fully functional. Companies are pursuing two main strategies:
- Microencapsulation, where cells are immobilized individually or as small clusters, in tiny blobs of a biocompatible gel.
- Macroencapsulation, in which greater numbers of cells are put into a much larger, implantable device.
ViaCyte, which recently partnered with Johnson & Johnson, launched its first clinical trial in 2014. The trial involved a micro-encapsulation approach that packaged up the company’s partially differentiated, ESC-derived cells into a flat device called the PEC-Encapsulation. About the size of a Band-Aid, the device is implanted under the skin, where the body forms blood vessels around it. “It has a semipermeable membrane that allows the free flow of oxygen, nutrients, and glucose,” says ViaCyte’s chief executive officer, Paul Laikind. “And even proteins like insulin and glucagon can move back and forth across that membrane, but cells cannot.”
The trial showed that the device was safe, well-tolerated, and protected from the adaptive immune system—and that some cells differentiated into working islet cells. But most cells didn’t engraft effectively because a “foreign body response,” a variant of wound healing, clogged the PEC-Encap’s membrane and prevented vascularization. ViaCyte stopped the trial and partnered with W. L. Gore & Associates, the maker of Gore-Tex, to engineer a new membrane. “With this new membrane,” says Laikind, “we’re not eliminating that foreign body response, but we’re overcoming it in such a way that allows vascularization to take place.” The company expects to resume the trial in the second half of this year, provided it receives the green light from the FDA.
Semma is also developing macro¬-encapsulation methods, including a very thin device that in prototype form is about the size of a silver dollar coin. The device is “deceptively simple, but it allows us to put [in] a fully curative dose of islets,” Sanna says.
Semma is also investigating microencapsulation alternatives. At the same time, the company is advancing toward clinical trials using established transplantation techniques to administer donated cadaver cells to high-risk patients who find it particularly difficult to control their blood glucose levels. These cells are infused via the portal vein into the liver, and patients take immunosuppressive drugs to prevent rejection.
Sigilon is working on its microencapsulation technology. Launched in 2016 on the back of work by the labs of Robert Langer and Daniel Anderson at MIT, the company has created 1.5-millimeter gel-based spheres that can hold between 5,000 and 30,000 cells (Nat Med, 22:306–11, 2016). Each sphere is like a balloon, with the outside chemically modified to provide immune-protection, says Sigilon chief executive officer Rogerio Vivaldi. “The inside of the balloon is full of a gel that creates almost a kind of a matrix net where the cells reside.”
In 2018, shortly after partnering with Eli Lilly, Sigilon and collaborators published research showing that islet cells that were encapsulated in gel spheres and transplanted into macaques remained functional for four months. The company has not disclosed a time frame for a type 1 diabetes trial “but we’re moving pretty quickly,” says chief scientific officer David Moller.
To conclude, all three firms hope to extend their work to treat some of the 400 million people worldwide with type 2 diabetes, many of them eventually benefit from insulin injections. The recent endorsements from big Pharmaceutical underline the real progress in beta-cell transplants, says Aaron Kowalski, a molecular geneticist and chief executive officer at JDRF, a foundation based in New York that has funded research at ViaCyte and academic labs whose work has been tapped by Semma and Sigilon. “These companies all realize that if they don’t do it, somebody else will. It’s hard to predict exactly when, but somebody is going to make this work.”
A lot of viruses that has taken a toll on life, the ebola virus in Africa, The Nipah virus of Nipah and the most recent one corona virus that left china running helter skelter all seemed to have originated from bats. During the course of the virus epidemic in Wuhan where it was first detected, some Chinese researchers in Wuhan examined some patients affected in that area and then took samples of the virus.
They did findings on the genetic sequence of the virus with other viruses that were known. The corona virus surprisingly had a 96% match with the horseshoe bats that are dominant in the southwest of china. The research findings were then published in a study on February, 2020.
A virologist Vineet Menachery from the university of Texas Medical Branch at Galveston though not affiliated to the study said “They’re too close in terms of their pure genetics to say they’re not related, or that they didn’t have a common ancestor.”
Menachery was a reputable virologist and had done other research works. He contributed to the theory that the spread of the corona virus must have been from these bats to humans. And possibly must have had another animal that served as an intermediary for the spread.
This same thing had happened with other forms of corona viruses as noted in the case of SARS (Severe Acute Respiratory Syndrome) an outbreak that took place in 2002-2003 where civets, a mongoose family member were infected with the bat corona virus and spread as humans bought them for food.
Another case was the MERS (Middle East Respiratory Syndrome) outbreak. This one happened in 2012 and was as a result of infected camels from the virus. People who ate undercooked meat of camels and as well drank the raw milk of camels were all affected.
So why is it that there are so many diseases that are spread from bats?
Its no doubt, bats have a lot of viruses that they carry with them. And these viruses in their variety are spread and manifests its tolls on people. Scientist are not sure why this is the case as confirmed by Kevin Olival, a research vice president as EcoHealth Alliance, a non-profit organization based in the U.S. He went further to say that it may have something to do with the family of the viruses carried by the bats. So you know, there are over 130 different families of viruses that bats do carry around.
And then, most bats and humans do come in contact through several means. The millions of populations of bats are ubiquitous to all the continents apart from in antartica. Rebekah of Colorado State university who researched infectious pathogens said “There’s a lot of viruses we’re finding in bats because there’s a lot of bats out there.”
They move about in multitudes and live in colonies of large populations. Some these members live in caves and share caves and trees where there can be a contact between humans and bats. Hence, these viruses can spread from these bats to humans.
Despite their sizes, bats have relatively long lifespans and can live over 30 years.”So there’s a long time for them to be persistently infected with the virus and shed it into the environment,” Kading says. The mode of mechanisms for these viruses are through urine, saliva and feces of bats. The outbreak of Nivah that happened in Bangladesh was linked to the sap of a date palm gotten from some trees that some bats licked and had infested with their urine.
Reading through all these, it is not absurd to wonder why the bats themselves do not get affected by the viruses they carry.
The answer to that question is based on the fact that the bat is the only flying mammal in the world. Their body metabolism and process quite differ from that of normal mammals too. When bats fly, their heart rates rise to about a thousand beats per minute with a temperature rise of about 100 degrees Fahrenheit. Linfa Wang a student of bat viruses at Duke-NUS Medical School in Singapore says that when these signs manifest in other mammals, they are signals that can trigger death. But this is not the same case for other bats. This is a lifestyle for them, every day.
Their system is also capable of producing molecules that other organisms do not have. The molecules carry out repair functions and prevent cell damage. This makes their system a bit irresistible to infections and also make them recalcitrant to viruses and resilient to diseases such as diabetes, cancer and other health conditions.
This is a prove that the manifestation of viruses in mammals is not always as a result of the virus itself, but as a result of the body’s reaction to the presence of such a virus that makes us ill by triggering other chain reactions, as Wang explains.
Olival at EcoHealth explains that these bats have coevolved with these viruses and it is not totally their fault that we humans are infected and affected by these viruses. The actual problem is when the viruses move from their species to other species of mammals which is also fostered by human activity.
Naturally, it would be hard for most animals and mammals to cross paths. But Olivial says that the presence of some activities and availability of exchange platforms made available by humans can allow such interaction to occur. She gave an example using wildlife markets like the one in Wuhan, where a bat could be mixed up with a civet. Who later on come in contact with humans – eg. Butchers who do not observe proper hygiene and protection from animal blood.
“The way that we’re coming into contact with these animals, hunting, selling, and trading them is to a scale that really we haven’t seen before,” he says.
Investigative teams did some in-depth search and they discovered some traces of this virus in 22 stalls and in a garbage truck that was found at Huanan Seafood Market right there in Wuhan, a place known for booming trade for live animals. This discovery led to shutting down the market as it was tied to majority of the cases.
The intermediary animals to this viruses are still a mystery, but it is clear that some of these animals are prone to interact more with humans. This is why when they are infected, the likelihood for human infection is widened. These other infected animals can sneeze, urinate, be cooked as food or even owned as pets.
Bats are not just vectors for viruses, they play an important role in balancing the eco-system. They feed on insects and fruits and are active agents of pollination. In fact, Wang believes that since these bats have successfully coevolved with these viruses, there is every possibility that they can be the agents that can lead to the cure and provision of therapies for these viruses.
Because of the complex nature of wound healing process, an injury on the skin can pose several challenges and are likely pose complications especially when they are acute. They can as well deteriorate from acute to chronic conditions which will require external intervention best understood by a specialist physician to get the area affected by the wound under normalcy.
The complexity of wound healing and research remains an ocean of knowledge that is continuously researched intensely to uncover depths of wound healing techniques and interventions. Hence, this report contains an introduction and details to the use of a new medical innovation called Gcells used primarily for the management of wounds in their different etiology.
In a case where the process of wound healing seemed difficult, Gcells proved great effects an attribute to their design and working protocol. Gcells are conditioned to work with an enriched suspension of progenitor cells that can efficiently aid tissue repair process. In this case report, two subjects were used as donors and acceptors of these micro-grafts.
The skin is an outer layer of the body, offering protection to the underlying layers. A wound breaks this layer and inhibits the various functions as well as expose or also break the underlying layer of tissues. Repair processes are inherent and part of homeostatic processes of the body to try to restore the skin back to its normalcy in structure and in function.
The basics for the skins repair mechanism is represented by a cloth and an inflammation where vessels dilate and monocytes activate leading to breakdown of necrotic tissues. This basic process can be inhibited or delayed by a number of varying factors that lead to deteriorative transformation of acute wounds to chronic forms. But if there is no alteration in the repair process, Mesenchymal cells kickstart proliferative process and begin to repair and restructure the affected tissues starting from the base. At the same time epithelial tissues begin to grow around the wound leading to a final step of the healing process. In this final stage, remodeling of the skin structure is primary and then maturation of a scar.
These processes are efficient best in certain conditions which if affected by factors such as cardiovascular ailment, diabetes, bacterial or any other genre of infection, can inhibit these processes.
Hence, it is necessary to understand in details these processes if there is going to be development or innovation for effective healing processes. Just as stated above, during the proliferative phase of wound healing, Mesenchymal cells are the key role players. Their structure includes a Mesenchymal stem cell (MSCs), multi potent in nature and offer supportive, therapeutic and trophic functions. They are also able to release viable trophic, anti-inflammatory cytokines and anti-apoptotic molecules that offer protection during the repair of wounded skin. MSCs also possess subpopulations that are stem-like nature commonly referred to as “side population” (SP) they have been found out to be enriched in over 1000-fold of progenitor cells and multipotent stem cells and as well exist in tissues and tumors. SP exists in a variety of organs and tissues, after an original discovery to be prominent in the bone marrow of a mouse. The organs with SP include the lung, liver, brain, mammary gland and in skeletal muscles.
In other discoveries, it was discovered that they probably may also be isolated in other tissues of the body. This discovery was in an in vitro and in vivo experiment when Dental Pulp Stem Cells (DPSCs) showed capability to differentiate into osteoblasts and built a woven bone by forming an Extracellular Matrix (ECM) secreted by the osteoblasts. The experiment drew results on the both the quality and quantity of the matrix formed by the DPSCs in the in vivo and in vitro experiment using Stem cells and accompanying biomaterials.
Thus proved that dental pulp holds potentialities of therapeutic strength and a rich source of progenitor/autologous cells that can be used to aid healing processes even applicable to regeneration of craniofacial bones.
This is the evidence that supports the working principle of Gcells innovation. Gcell successfully separates this side population with a size of 50 micron. At this cell population, they can form autologous micro-grafts and can either be used alone or alongside biomaterials prepared in a biocomplex ready for use when necessary.
In this case report, two subjects were used as donors and acceptors of these micro-grafts for enhanced healing of complex wounds through autologous micro-grafts using the Gcell.
Clinical case 1
The first case involves a woman at age 50 who does not have any diseases or disorders. She underwent a laparoscopic gastric bypass surgery and was doing well considering parameters of weightloss. Two years later she moved in for abdominoplasty bariatric. Later on, post complications showed preeminence of necrosis which was discovered after first medical examination were about 150 to 200cm2 at the end of the flaps. An initial necrosectomy showed an intense loss of tissue and we furthered to place the wound on VAC therapy and the patient in active participation of this therapy for one week then at home as an outpatient.
As an outpatient, there was improved and progressive wound cleansing while granulated tissues around the base area were cleared.
The VAC therapy after 2 months still left the margins of the wound deteriorated and surrounding areas not in axis with skin surface.
The Gcell protocol kickstarted after consent from the outpatient. We started by collecting a 3 cm2 skin sample from the patient for the purpose of obtaining the cell suspension needed to be injected to the granulation tissue (figure2).
We followed up with conventional wound treatment as in cleaning and replacement with sterile gauze dabbed with Vaseline. The wound area began to improve in both healing progress and general appearance. In two months, the undermined area disappeared as well as leveled to the axis of the skin surface. 2 months later, the wound reduced to a very little scar that is mild and smoothed compared to the initial condition. (figure 3).
A man who suffered liver cirrhosis, hiatal hernia and diabetic as well at the age of 78. Complex surgery was carried out and distal esophagectomy was performed. But hiatal hernia was not decreased into the abdomen, so he was booked up for corrective surgery. During the intervention the adhesions correlated to the previous abdominal operation and led to opening the colon for resection. Some postoperative complications by the appearance of entero-cutaneous fistulas, related to a colonic anastomosis dehiscence. A second intervention was inevitable hence a ileostomy protection and repackaging of colonic anastomosis. We closed the laparotomy using a biological prosthesis. But we met further complications from ascetic failure that needed intensive care hepatology.
Patient’s condition that included poor liver synthesis had its toll on the healing of the surgical wound. Just as the first case, necrotic tissues grew around the biological prosthesis. We conducted necrosectomy and the biological prosthesis was left half exposed. (Figure 5).
Further treatment of the wound using advanced medication helped cover the biological prosthesis with granulation tissue (figure 6).
Plastic surgeons conducted evaluations on the patient and the choice to do a rotation flap did not seem so appropriate. VAC therapy was used on the wound for about 15 days even though the device wasn’t efficient enough to maintain supposed suction in the presence of ileostomy. We proceeded to treat the patient further with Gcell protocol when wound dimension progressed to about 250cm2. The tissue granulation was of right margin near the ileostomy improved even though it appeared to be undermined. In summary, Gcell protocol has proved a great level of efficiency in healing and restoration of damaged tissues. This progress is certain to open way for employment in the clinical practice that involves the treatment and management of acute and chronic wounds and in any other field of medicine that will inevitably need an instrument to repair lesion on tissues.
Discussion and conclusion
We made it clear earlier in this document about the efficiency of Gcell protocol in its aid to wound healing especially for wounds that are likely to develop from acute to chronic conditions. The working principle for the Gcell used to obtain the viable progenitor cells used for the micrografts relies on one individual as both the donor and the acceptor. This will help to reduce complications that are related to implants or injected micrografts that are non-autologous. Gcell is flexible and can be used both during in operating rooms as well as in ambulatories. This innovation is vastly spreading and currently used in the fields of oral-maxillo-facial field proven by recent studies even though a greater area of its application widespread and acceptable in plastic surgery, dermatology and orthopedics.
Conclusion of this report brings to clarity in demonstration, an efficient, useful and low-risk innovation in the field of medicine, useful for areas in wound management and healing. However, the viability of the Gcell product still needs to be texted on subjects with different conditions and perspectives. But we assure that this device will prove to be a better therapeutic approach in the field of medicine in improving healing of complex wounds. This confidence lies in the excellent features and working principles of this device in obtaining cell suspension, flexibility, facility for procedure and more importantly, the cost. This will help reduce the use of exorbitantly prices devices for advanced medication. In summary, apart from introducing an efficient innovation in the medicine. Gcell has the potentialities to offer employment on clinical procedures that will help aid in the management of wounds no matter how the case may be.
One of the amputating surgeries in the field of medicine is a knee replacement. It involves removing the knee joint and replacing it with a modified prosthesis. However, several modifications of this surgery have been introduced into the high-powered world of surgery, including several alternatives for knee replacement. In this article, we are going to review the several modifications and knee replacement alternatives therein.
What is Knee Replacement?
Knee replacement, also known as knee arthroplasty, is a surgical procedure that involves the amputation or cutting out of a knee joint, the bones reams by a doctor, especially due to accidents or joint ailments such as arthritis. When the bone is removed, it is then replaced with a prosthetic device. Knee replacement can be partial, where selected or affected parts of the joints can be removed, such as the medial, lateral, and anterior compartments can also be removed and replaced with a modified prosthetic.
Why Should You Be looking for a Knee Replacement Alternatives?
Due to the dynamics of the human body, what works for the goose may not necessarily work for the gander. Certain post-symptoms of a knee replacement can be unbearable for most patients.
Pain After Knee Replacement.
Due to pain in the knee joint, a lot of patients embark on this old-time surgery to help reduce the pain they feel around their knee. But it is worthy of knowing that a substantial number of these patients still continue to feel pain after this audacious surgery. In a survey done by the government, 40% of patients that underwent knee replacement experienced miniature pain for over 3-4 years, while another 44% still felt some 3-5/10 degree of pain in 3-4 years. So, it is not worthy of looking in the direction of knee replacement alternatives in order to solve knee pain.
Knee Replacement Risks.
There is a risk in everything that we do, business, taking a walk, climbing a hill. Same way, certain risks exist in knee replacement which are:
- Patients become more susceptible to heart attack and stroke immediately after knee replacement surgery.
- Increased levels of metals in the blood.
- Allergic reactions to the prosthetic material.
- Possibility of infection.
- Reduced activity of the patient as they thrive to become accustomed to the new prosthesis.
Even though social media and digital marketers paint a vivid picture of beautiful seniors riding a bike, continuing in their daily activities and hobbies, but this may not be true for everyone; in a study conducted by the government, there was seldom activity by patients after knee replacement surgery. Another study showed that patients who weren’t running before a knee replacement surgery couldn’t run after the surgery. But there are always two ways to everything; some other patients also showed an increase in physical activity after their surgery.
What are Knee Replacement Alternatives?
Steroids are made up of corticosteroids and cortisone. These corticosteroids carry out an anti-inflammatory function to prevent swelling around the knee regions as well as help reduce pain. But they do have a side effect; they destroy cartilage and may not be efficient as they are thought to be. If you are considering this knee replacement alternative, you probably should bear in mind that they do not offer long term remedies. Steroid injections are viable for knee replacement needs caused by arthritis but may proffer short-termed solutions.
Viscosupplementation is also another knee replacement alternative. They are in the form of gels for the knee, also knowns as hyaluronic acid varying across different brands in the market, likes of SynVisc, OrthoVisc, Supartz, and Euflexxa. They are administered to the patient, but a quick question one would ask is if really the shots help. The variations of results all over the web show support both sides of the notion. But one peculiarity of these results is that none says that they are hurtful or damaging as the steroid injections rather that they give a better solution to knee joint arthritis patients. In my own experience, these injections are efficient only when administered a few times, after which they begin to diminish in effects. The first dose may offer relief for some time, but a dose a far-reaching as the sixth dose may not offer any remedial effect at all.
Knee Nerve Ablation
Knee Nerve ablation is another breakthrough in the surgical world. Knee Nerve Ablation involves the use of technology to carry out a process where the specialist probes the nerves around the joint and passes electrical energy that is used to ablate (destroy) them. The work of these nerves is to relay signals from that region of the knee to the brain. So this technique deadens these nerves, and as such, you don’t feel any pain till those nerves grow back. The research on this type of knee replacement alternative is only a handful. Hence, they cannot conclude on the long term results since most of the studies on this new breakthrough are in their early stages.
Orthobiologics incorporation around the knee regions helps to enhance the healing of the knew joint or reduce the consequent degradation of orthopedic tissues. Orthobiologics are also knee replacement alternatives and can be gotten from the patient as autologous or a donor as allogeneic. The two primary derivations of orthobiologics are the PRP and the BMC short for Bone Marrow Concentrate. Another derivation that is commonly used is derived from natal tissues as in amniotic or umbilical cord. Just as the nerve ablation, the research on this type of knee replacement is at its early stages.
Platelet Rich Plasma (PRP)
We mentioned PRP earlier while discussing orthobiologics. PRP’s stand for Platelet-rich plasma that can be gotten from the patient. They contain healing factors that allow them to foster cartilage repair as well as reduce inflammation and balance the chemical dynamics of the knee. A lot of studies support the efficiency of PRP as knee replacement alternatives but may not offer much help when the arthritis is severe.
PKA (Percutaneous Knee Arthroplasty)
PKA (Percutaneous Knee Arthroplasty) comes in handy for severe cases of arthritic pain. This procedure involves the injection of rich bone marrow concentrates gotten from the patient or from a donor into the lax ligaments or other affected areas such as damaged meniscus tissues and tendons. This procedure is intricate and uses an ultrasound and fluoroscopy guides as compared to other quick knee shot techniques. Research proves that this method works pretty well, even in extreme cases of knee arthritis. This procedure also produces a lasting effect for about 2-7 years before the need for repetition.
Here you go!! Knee replacement alternatives. You sure would want to consider some of the alternatives; likes of PKA, PRP, and Bone Marrow concentrates that proffers a long-lasting solution.
