Stem cells: Mankind’s answer to Prometheus’ vulture

Prometheus is a Titan in Greek Mythology, best known as the creator of mankind and it’s greatest benefactor. He transgressed the law of gods and stole fire from Mount Olympus for the sake of humankind, for which he received a brutal punishment from Jupiter. Jupiter had him chained to mount Caucasus, where a vulture would prey on his liver daily. Legend has it that his liver renewed as quickly as it was devoured, which captures the body’s remarkable regenerative capacity. Although humans possess natural regenerative capacities albeit at a much lower level, it is still a fascinating phenomenon. But the fact that not every organ in the human body can be regenerated at will is what sets us apart from the Titans in Greek Mythology. But recent advances in the field of regenerative medicine with stem cells has challenged the concept of organ-specific regeneration. This has been realized by discoveries wherein multipotent/pluripotent cells hereby referred to as stem cells have been isolated from many tissues of the body, even from some, such as the nervous system, that have historically been considered incapable of regeneration. While the astonishing pluripotent characteristics of embryonic stem cells has generated much interest in the scientific community, the field has received considerable backlash due to various ethical concerns. This is exactly when researchers intensified their efforts in identifying similar cell lineages in the adult that may contribute to self-renewal. Various reports generated on the versatility, plasticity and the self-renewing capacity of adult stem cells have made them a subject of immense interest in the scientific and general community alike. Harnessing the power of adult stem cells for the repair and general replacement of damaged tissue is fast becoming a reality. The use of stem cells to repair damage to eyes (Macular degeneration) or to replace skin that has been subject to severe burns is already underway. The use of stem cells to restore bone marrow in cancer patients undergoing chemo and radiotherapies is also widespread in use. The extensive usage of stem cells in regenerative/reparative treatments is an ever evolving phenomenon and everyone should realize and appreciate the power of stem cells. All the stakeholders here at Transcell strongly believe in the power of these super cells and constantly strive towards educating the general public about the same.

A 20 year old patient suffering from Becker’s Muscular Dystrophy who had intense muscle weakness and had difficulty in performing his activities was treated with autologous BMMNC transplantation The BMMNCs were transplanted via intrathecal and intramuscular routes. Over 9 months post transplantation improvement in muscle strength, respiratory functions was observed. Suggesting that stem cell therapy combined with rehabilitation has the possibility regenerating muscle fibers and decreasing the rate of progression of BMD.

Another group was able to successfully transplant iPSC induced pluripotent stem cells. These cells were derived from skin fibroblast which were transformed into a sheet of retinal pigment epithelial (RPE) cells. This sheet was transplanted into a patient with neovascular age-related macular degeneration. The transplantation has ensured no further degeneration and retained visibility of the patient.

Periodontitis a condition by which tooth-supporting structures are progressively destroyed and this disease is leading reason behind tooth loss in adults. Autologous periodontal ligament stem cells (PDLSCs) along with grafting materials was used for guided tissue regeneration (GTR) to treat periodontal intrabony. The study showed an increase in the alveolar bone height and decrease in the bone-defect depth.

Mesenchymal stem cells were used as a therapeutic option for knee osteoarthritis.  BM-MSCs: Bone marrow derived mesenchymal stem cells in combination with hyaluronic acid was used for the treatment. Post transplantation here there was an evident improvement observed. The patients had improved motion range; the damage in the joint had decreased.

In another recent study patients with chronic stroke underwent surgical transplantation of modified bone marrow – derived mesenchymal stem (BMMSC), a significant improvement was documented in all the patients; all the patients showed an improvement at the standard Stroke Scale, a substantial increase from the baseline with reduction in disease severity, thus confirming the regenerative capabilities of the transplanted cells.

Stem cells: The hope and the hype
Everyone irrespective of their background seems to be talking about stem cells these days. Stem cells have garnered much attention because they can turn into all different types of cells and that too on demand. While the implications for the use of stem cells in medicine are profound, there are still a lot of practical barriers that need to be streamlined for realizing the full potential of stem cells as therapeutic tools. The current issue of Transcomm is dedicated to making sure the reader realizes the true potential of stem cells i.e what they can actually do and what they cannot. Our goal here at Transcell is to educate the general public about the significance of storing their loved ones’ stem cells which could come handy in the future when the donor or the related family develops a life threatening disease for which stem cells are the only treatment options. Often times, the term stem cells is used out of context and like any other novel treatment modality, the promise of curing any disease using stem cells should be taken with a pinch of salt. We will look into the history of stem cells, where and when it all started before we touch upon various case studies and novel treatment methods that have been made possible thanks to the advent of stem cells.

The Russian histologist Alexander Maksimov is credited with coining the term “stem cell” in 1908. Back then, the mere idea of self- renewing cells existing inside the body offered a ray of hope for many patients and researchers alike. Only after the Second World War were scientists able to trace the lineage of a particular cell using radioactive markers which helped noted scientists like Altman, McCulloch and Till to observe and document the presence of self-renewing cells in animal models. Since then, much of the research on so-called self- renewing cells/stem cells has been carried out mainly in mouse and primate models. The fascinating properties of stem cells, such as the ability to self-renew unlimitedly together with asymmetric division and plasticity have heralded the dawn of a new era of regenerative medicine. New treatment modalities using stem cells (stem cell therapy) while offering a very cost effective therapeutic approach also help tackle some rather debilitating diseases where in conventional treatments have failed to deliver. For example cell-replacement therapies using stem cells have been gaining importance in the field of Diabetes, wherein insulin-producing cells could be generated from stem cells which could then be grafted into the pancreas of the patient. Similarly, research on adult mouse brains has shown that certain brain disorders characterized by the loss of neurons (Parkinson’s etc) could be corrected by grafting stem cells into developing brains which would then differentiate into neurons and restore the normal functioning of the brain. The two examples mentioned above are just a tip of the iceberg. The list of uses of stem cells in regenerative/reparative medicine could be exhaustive. After reading this particular edition of Transcomm, we hope that the reader would agree with us that the hype surrounding stem cells is in fact true and that the hopes of treating various fatal, non-fatal and emerging diseases is possible using stem cells.

India tops in development of stem cell treatment, also it can be a pathbreaking therapy for diabetes, Autism

Researchers and experts believe India has been rapidly making strides in the field of stem cell therapy followed by countries like China and Japan. The lack of awareness that stem cells could be used for treating various incurable diseases has been hampering its growth as an alternative treatment modality. Diabetes and Autism, two of the major issues plaguing India could be tackled with the usage of stem cells. Using a patient’s own stem cells (autologous transplant), new Beta cells could be generated in the pancreas. This type of transplantation is also free of any complications that might arise due to graft rejection. Umbilical cord tissue derived stem cells are considered to be ideal for treating Autism. Currently clinical trials are underway to treat Autism using umbilical cord tissue stem cells. The advantage of using umbilical cord tissue derived stem cells is that the collection of stem cells is not as laborious as collecting adult stem cells and moreover, the stem cells collected right after birth are more potent than their adult counterparts.

 

Skin stem cells used to generate new brain cells Study to advance understanding of the role of microglia in Alzheimer’s disease
Date:
April 25, 2017
Source: University of California – Irvine
Summary: Using human skin cells, neurobiologists have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease

Using skin cells derived from a patient, neurobiologists at the University of California, Irvine have managed to generate one of the major types of brain cells called Microglia. Microglia play a pivotal role in preserving the function of neural networks while also playing an important role in injury and disease. The group led by EdselAbud, Wayne Poon and Mathew Blurton Jones of UCI have used a series of differentiation factors that helped the stem cells derived from skin to transdifferentiate into Microglial cells. Recent studies on Microglia have implicated their role in Alzheimer’s. The current research would help unravel the connection between Microglia and Alzheimer’s and would also lead to better drug development.

New stem cell invented that can grow into any tissue in the body, study finds

Researchers from China and the Salk institute have successfully created a new kind of stem cell, which is more versatile than the ones that are available now. The new cell named Extended Pluripotent Stem cell (EPS) can give rise to every cell in the body, researchers claim. The EPS cell not only can give rise to every cell in an embryo and adult organism, but also can make the placenta and other extra-embryonic tissues needed for the embryo to survive and grow. This ability enables the new type of stem cell to produce complete embryos and offspring, the scientists said. This research would enable researchers create transgenic animal models for analyzing various diseases with ease. Moreover, chimeras could also be developed with human cells for cultivating organs in the lab which could eventually be transplanted back into patients with organ failure.

A research team at Sahlgrenska Academy in Sweden has managed to create cartilage tissue from stem cells using a 3D printer. The fact that stem cells survived the printing is seen as a major success in itself and could potentially serve as an important step in the quest to 3D-print body parts.The research team used cartilage cells taken from humans in connection with knee surgery. Subsequently, the cells were reversed in their development under lab conditions to become so-called pluripotent stem cells, which are cells that have the potential to develop into any kind of cells. Later, they were enclosed in a structure of nanocellulose using a 3D printer. After printing, the cells were treated with growth factors to form cartilage.On top of being a major technological achievement, the study represents a major step forward for the artificial creation of human tissue using stem cells and 3D bioprinting. In the not-too-distant future, 3D printers could be used for repairing cartilage damage or as a treatment for osteoarthritis, which causes the degeneration of joints.

 

Japanese man is first to receive ‘reprogrammed’ stem cells from another person

World-first transplant, used to treat macular degeneration, represents a major step forward in movement to create banks of ready-made stem cells.

David Cyranoski 28 March 2017

On 28 March 2017, a Japanese man in his 60s became the first person to receive cells derived from induced pluripotent stem (iPS) cells donated by another person. The surgery is expected to set the path for more applications of iPS-cell technology, which offers the versatility of embryonic stem cells without their ethical taint. Banks of iPS cells from diverse donors could make stem-cell transplants more convenient to perform, while slashing costs. IPS cells are created by removing mature cells from an individual (for example, from their skin) and reprogramming these cells back to an embryonic state. They can then be coaxed into a type of cell useful for treating a disease.In the latest procedure, performed on a man from the Hyogo prefecture of Japan, skin cells from an anonymous donor were reprogrammed into iPS cells and then turned into a type of retinal cell, which was in turn transplanted onto the retina of the patient, who has age-related macular degeneration. Physicians hope that the cells will stop the progression of the disease, which can lead to blindness.

SPRAY-ON SKIN: ‘MIRACLE’ STEM CELL TREATMENT HEALS BURNS

WITHOUT SCARRING

Pennsylvania state trooper Matt Uram was talking with his wife at a July Fourth party in 2009 when a misjudged spray of gasoline burst through a nearby bonfire and set him alight. Flames covered the entire right side of his body, and after he fell to the ground to smother them, his wife beat his head with her bare hands to put out his burning hair.From the hospital, Uram was transferred to the Mercy Burn Center in Pittsburgh, where doctors removed all of the burned skin and dressed his wounds. It was on the border between a second- and third-degree burn, and he was told to prepare for months of pain and permanent disfigurement. Not long after this assessment, however, a doctor asked Uram if he would be willing to take part in an experimental trial of a new device.The treatment, developed by German researcher Dr. JörgGerlach, was the world’s first to use a patient’s stem cells to directly heal the skin. If successful, the device would mend Uram’s wounds using his body’s ability to regenerate fully functioning skin. Uram agreed to the procedure without hesitation.Five days after the accident, surgeons removed a small section of undamaged skin from Uram’s right thigh—about the size of a postage stamp—and used it to create a liquid suspension of his stem cells that was sprayed in a fine mist onto the damaged skin. Three days later, when it was time to remove the bandages and re-dress the wounds, his doctor was amazed by what he saw. The burns were almost completely healed, and any risk of infection or scarring was gone.

Medically Approved Regenerative Treatments Using Dental Stem Cells

Teeth, which happen to be the most natural and noninvasive source of stem cells owing to their convenience and affordability to collect hold promise for a range of difficult to treat  medical indications. The regenerative capacity of dental pulp derived stem cells has been a topic of utmost interest to clinicians and researchers alike in the field of regenerative medicine. The story of dental stem cells dates back to 2003, when Dr. Songtao Shi, a pedodontist discovered baby tooth stem cells in the deciduous teeth of his six year old daughter and named the cells as stem cells from the human exfoliated deciduous teeth (SHED). Dental Pulp Stem Cells or DPSCs as they are commonly referred to, are found within the ‘‘cell rich zone’’ of the dental pulp. Their multipotent nature can be attributed to their origin from the neural crest. Owing to their multipotent nature, these DPSCs can effectively differentiate into many cell types which include adipocytes, neurons, chondrocytes and mesenchymal stem cells under specific stimuli. Since they can be found in both adults and children alike, their use in regenerative and patient specific treatment of certain ailments has been gaining rapid momentum. One of the major advantages of DPSCs over  umbilical cord/blood stem cells is that the dental stem cells are derived from the deciduous and permanent teeth (wisdom/corrective) and can be collected later after birth unlike their umbilical cord counterparts. Collection of teeth for dental pulp and isolation of stem cells from the pulp can be carried out without raising any ethical red flags as the procedure is very simple/non-invasive without any associated mortality or morbidity. Recent advances in the field of dental stem cell clinical research have made it possible to employ them in reparative and regenerative roles. This newsletter is an effort to bring to the reader’s attention some of major advancements in the “close to reality of DPSCs in clinics”. We hope the reader while appreciating the significance of DPSCs would strongly consider storing their loved ones’ about to fall milk teeth derived stem cells even if the loved ones Cord/blood were banked as the medically approved applications are different for different sources.

TOOTH (The Open study Of dental pulp stem cell Therapy in Humans): Study protocol for evaluating safety and feasibility of autologous human adult dental pulp stem cell therapy in patients with chronic disability after stroke

Stroke represents a significant global disease burden. As of 2015, there is no chemical or biological therapy proven to actively enhance neurological recovery during the chronic phase post-stroke. Human adult dental pulp stem cells present an exciting potential therapeutic option for improving post-stroke disability. TOOTH (The Open study Of dental pulp stem cell Therapy in Humans) will investigate the use of autologous stem cell therapy for stroke survivors with chronic disability, with the following objectives: (a) determine the maximum tolerable dose of autologous dental pulp stem cell therapy; (b) define that dental pulp stem cell therapy at the maximum tolerable dose is safe and feasible in chronic stroke; and (c) estimate the parameters of efficacy required to design a future Phase 2/3 clinical trial. The primary outcomes to be measured are safety and feasibility of intracranial administration of autologous human adult DPSC in patients with chronic stroke and determination of the maximum tolerable dose in human subjects. Secondary outcomes include estimation of the measures of effectiveness required to design a future Phase 2/3 clinical trial.

Human dental pulp stem cells (hDPSCs) as treatment for periodontal disease

ISRCTN12831118 DOI 10.1186/ISRCTN12831118

 Periodontitis, or periodontal disease (PD) is a very common chronic gum infection that damages the soft tissue and destroys the bone supporting the teeth. It can lead to tooth loss, difficulties chewing, poor appearance of teeth and gums and it can even increase the risk of a heart attack or stroke. It is caused by the build-up of bacteria in the mouth which, over time, combines with saliva and small food particles to form a sticky film over the teeth, called plaque. The bacteria in the plaque can result in gum disease, leading to swollen, painful gums. If not treated, this gum disease will get worse and will develop into periodontitis. Up to 90% of people over the age of 75 have PD and it carries with it a high risk of other health complications. Current treatments are not very effective. Experimental and clinical data suggest that human dental pulp stem cells (hDPSCs) are capable of regenerating periodontal structures (soft tissues and bone supporting the teeth) regardless of their autologous (coming from the person themselves) or allogeneic origin (coming from a donor). This study is looking at the effect of in situ treatment with hDPSCs on periodontal disease, markers of oxidative stress and inflammation in aging adults.

Feasibility of the Preparation of an Advanced Therapy Medicinal Product for Dental Pulp Regeneration (Pulp’R)

ClinicalTrials.gov Identifier: NCT02842515

Current endodontic treatments are based essentially on the ouster of parenchyma in case of trauma or irreversible pulp inflammation. These situations typically affect immature teeth in subjects aged from 8 to 15 years. Consequently, loss of a functional pulp is leads to discontinuation of root development and apical closure. The challenge for the clinician in the management of such situations is then preserving a pulp vitality. But current practices consist in a filling of the endo-canal system with an inert or semi-inert material. In this case, no pulp vitality is present. New treatment methods are needed. The objective Pulp’R is the study the feasibility of preparing an autologous combined advanced therapy medicinal product (ATMP) for dental pulp regeneration in the patient with irreversible pulp inflammation or dental trauma.

Periodontal Regeneration of Chronic Periodontal Disease Patients Receiving Stem Cells Injection Therapy

ClinicalTrials.gov Identifier:NCT02523651

The purpose of this study is to evaluate the safety of clinical injection of allogeneic human dental pulp stem cell (DPSC) in local infected periodontal tissue and determine whether injection of allogeneic DPSC is a effective way in the treatment of chronic periodontal disease.

3D printing has been touted as one of the most disruptive technologies that have been making waves during the 21st century. Despite some initial negative press about the technology, it has been quickly catching up generating a lot of buzz in the industry and general public alike. 3D printing is also called additive manufacturing wherein three dimensional solid objects are produced by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object. The ease of access to 3D templates, scanners, modeling software and printers that can print 3D objects has made our lives much easier.
From printing daily objects like furniture to complicated structures such as airplane and space shuttle parts, this rather exciting new technology slowly started becoming an integral part of our lives. According to Wohlers Report 2014, the worldwide 3D printing industry is now expected to grow from $3.07B in revenue in 2013 to $12.8B by 2018, and exceed $21B in worldwide revenue by 2020. The healthcare industry has quickly realized the full potential of this technology and researchers and clinicians are taking steps towards harnessing the power of 3D printing in improving the quality of human life. In the field of healthcare, 3D printing can be used in developing prosthetics, dental and bone implants, medical instruments, tissue and simple printed organs that can be used in transplants, pharmaceuticals production, nano-scale medicine and also in the printing of complex organs. As we are already aware of the Stem cells’ unique ability to produce both copies of themselves (self-renewal) and other more specialized cell types (differentiation) every time they divide, it would be exciting to see the marriage of stem cell therapy with 3D printing technology.
This newsletter is an effort to educate the reader about the potential applications of 3D printing technology using stem cells.
I am confident that the reader while appreciating the technological marvel that is 3D printing technology would also realize the potential of applying this technology in stem cell based regenerative therapies.

Nano Dimension Announces New 3D Bioprinting Subsidiary to Develop
Solutions fo rend Stage Renal Disease

Israel-based company Nano Dimension has a new announcement: the 3D printed electronics leader is creating a new subsidiary in order to advance its new 3D bioprinting initiative. In early 2016, the company partnered with Accelta, a stem cell culturing solutions provider, to successfully lab-test a proof of concept 3D bioprinter for producing stem cell-derived tissues.
Nano Dimension has been conducting market research into applications of its 3D bioprinting technology, and says that it will now be developing a platform to 3D bioprint both connective tissues and cells, which will be used to create biological structures that will function as human kidneys. The subsidiary will focus mainly on developing solutions for end stage renal diseases (ESRD) which ultimately lead to kidney failure.

3D bioprinted myocardial path could boost heart attack recover,
Korean Researchers say

A team of researchers in Korea has used a 3D bioprinter to make a myocardial therapeutic patch for treating ischemic heart disease. When attached to the heart, the 3D printed patch can generate new blood vessels and tissues. Professor Park Hoon-joon of the Seoul St. Mary’s Hospital and professor Jo Dong-woo of the Pohang University of Science & Technology, two of the lead researchers on the exciting bioprinting study, announced the results of their research on February 9, claiming that their 3D printed myocardial patch could radically change the way doctors approach the treatment of ischemia, a condition that results in low blood supply to the heart muscles or other organs.

To create the 3D printed heart patch, the researchers used cardiac extracellular matrices as a 3D printable bioink, with cardiac stem cells and mesenchymal stem cells configured in a double-cell arrangement. A vascular endothelial growth factor (VEGF), a signal protein that stimulates vasculogenesis and angiogenesis, was also introduced. The researchers say that this complex arrangement could hold the key to recovery from ischemic heart disease—at present, the five-year survival rate for patients is less than 50 percent.

Soon Printing a human heart on demand will no longer be sci-fi

Around the world, start-ups — like Tokyo-based Cyfuse Biomedical — are emerging to develop such breakthroughs in the field of regenerative medicine. It is a market projected to reach $101.3 billion by 2022.
Unlike conventional medicines and treatments, regenerative medicines have the ability to restore or heal the body’s own cells or create new body parts from a patient’s own cells and tissues, thereby eliminating tissue rejection and the excessively long wait for a donor organ.  This would be a remarkable scientific achievement, considering that in the United States alone 118,950 people are registered in the Organ Procurement Transplantation Network. Of these candidates, 22 die each day waiting for a lifesaving organ. The gap between supply and demand continues to widen, and it’s a problem many medical experts have called a major health crisis. Cyfuse has also started a clinical trial of a cartilage project, transplanting its stem cell construct into damaged articular cartilage that will gradually differentiate into cartilage and bone and regenerate the tissue.  Cyfuse is one of a growing number of tech start-ups trying to get a toehold in the global marketplace. The sector is blossoming due to innovations in stem cell therapy and tissue engineering. North America accounted for nearly 50 percent of revenue share of global market revenues for regenerative medicines in 2016. Europe is second, at US$24 billion, with Germany leading the region.

A new bio-ink for 3D printing with stem cell

Scientists at the University of Bristol have developed a new kind of bio-ink, which could eventually allow the production of complex tissues for surgical implants. The new stem cell-containing bio ink allows 3D printing of living tissue, known as bio-printing. The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed, and a sacrificial synthetic polymer used in the medical industry, and both had a role to play. The synthetic polymer causes the bio-ink to change from liquid to solid when the temperature is raised, and the seaweed polymer provides structural support when the cell nutrients are introduced. The team was able to differentiate the stem cells into osteoblasts – a cell that secretes the substance of bone – and chondrocytes – cells that have secreted the matrix of cartilage and become embedded in it – to engineer 3D printed tissue structures over five weeks, including a full-size tracheal cartilage ring.

Scientists from the Universidad Carlos III de Madrid (UC3M), CIEMAT (Center for Energy, Environmental and Technological Research), Hospital General Universitario Gregorio Marañón, in collaboration with the firm BioDan Group, have presented a prototype for a 3D bioprinter that can create totally functional human skin. This skin is adequate for transplanting to patients or for use in research or the testing of cosmetic, chemical, and pharmaceutical products.
This new human skin is one of the first living human organs created using bioprinting to be introduced to the marketplace. It replicates the natural structure of the skin, with a first external layer, the epidermis with its stratum corneum, which acts as protection against the external environment, together with another thicker, deeper layer, the dermis. This last layer consists of fibroblasts that produce collagen, the protein that gives elasticity and mechanical strength to the skin.

Stem Cells for Muscular Dystrophies

An orphan disease is a rare disease (according to US criteria, a disease that affects fewer than 200,000 people) or a common disease that has been ignored. But, the true definition not known by many is that a disease category that has not been taken up by any pharmaceutical industry to research on as it provides little financial incentive for the private sector to make and market medicines to treat or cure. Duchenne Muscular Dystrophy (DMD) is one such category in India that is totally not recognized by any healthcare schemes or research initiatives or NGOs or clinicians communities, worth a consideration for offering solace/treatment options to the suffering society. First visit to the doctor by the worried family is usually directed to a Neuro-physician, who would categorically declare that the affected kid will die soon and so medically advised to go home! Such is the level of compassion or practice or medical knowledge in the society that we are in.

Despite the urgent need for research in Orphan diseases, also requires a multidisciplinary  personalized approach like a community with participating, practicing Scientists, Clinicians and Parents of the affected kids in order to find innovative medical solutions gathering the expertise into centers of expertise.

Trying to get the facts, it is probable that Orphan diseases will never benefit from a specific drug or any available therapy, need for alternative research lines like Stem cells repairing the continuously degenerating muscles, inflammation associated is the only hope for this disease to be pursued. But, disruptive research has to happen translating into clinical application as patients can’t wait! For once if the investor community believes in scientific breakthroughs alleviating the human suffering as their ROI, it is Paradisso for human kind!

Here, I remain heavy with suffering patients in my thoughts!

January 2017 Transcomm highlights the Orphan disease DMD and possibilities with Stem cells to address the debilitating medical condition. Any application or research with stem cells is possible only if they were captured at the right event and stored in right condition.

So, Dear Readers, Please encourage, educate and evangelize your families, extended families, friends to store stem cells now!

S Dravida Transcell’s CEO

A study conducted by the Indian Society for Clinical Research (ICSR), states that 70 million Indians suffer from life threatening rare diseases. Although we have made immense progress in science and medicine, there is little that is known of the rare diseases prevalent in India, and a paucity of affordable therapy available for these diseases. Children form a part of nearly 50% of the population affected by these diseases, and only 30% of these children, live till the age of five.

Muscular dystrophy is one such rare genetic disorder that affects several in India. An X linked recessive disorder, this disease affects more males than females. While in most developed nations, MD patients survive till the age of 20-23, lack of awareness of this disorder in India has led to most MD children dying at the age of 13-17.

A neuromuscular disorder, which causes degeneration of a set of muscle cells, Muscular Dystrophy starts by destroying the skeletal muscle first, and then progressively deteriorates the internal organs as well. Of the several types of MD, Duchenne MD is the most common. It is caused by a mutation in the DMD gene. Several stem cell therapies have been proposed for DMD.

A loss-of-function mutation in the dystrophin gene, leads to DMD. In a study conducted by Dumont et al (2015), it was found that dystrophin association with a regulator of cell polarity, specifically serine-threonine kinase Mark2 protein, leads to its increased expression in satellite cells (activated muscle stem cells). Thus, absence of dystrophin leads to several intrinsic defects, such as inability to localize cell polarity regulator Pard3. These intrinsic defects, eventually impair muscle regeneration process, because if reduced generation of myogenic progenitors. Hence, it was concluded that the reasons for muscle wasting in DMD can be attributed to impaired regeneration of intrinsic satellite cell dysfunction and myofiber fragility.

In a study conducted by N. Ito et al (2016), it was found that treatment with leukocyte inhibitory factor (LIF) helped to maintain the undifferentiated state of satellite stem cells and also helped to maintain their transplantation efficiency. It was stated that since LIF has been reported to be functionally involved in muscle regeneration, and has alleviated the pathology of a mouse model of DMD, its role `in transplantation efficiency must be analysed. Research also stated that to improve the migration of the transplanted cells, a combination of LIF with other cytokines such as bFGF, would be required.

Ray of hope for Muscular dystrophy patients:

In a recent clinical trial, doctors at AIIMS have found a significant improvement in 20 patients who received stem cell therapy for treating MD.The report of the trial has also been published in the Journal of Stem Cells in its recent issue. Patients suffering from the disease die between ages of 13 to 21 years. According to Dr. B.S. Rajpoot, who led the clinical trial,  umbilical cord derived stem cells and IGF1 (a protein that in humans is encoded by the IGF1 gene) was used for stabilization as well as reversal of muscle damage.Initial observations over a period of three months have shown that stability in muscle function has improved and that there was a progressive decline in calf size of the DMD patients up to three years after stem cell transplantation, indicative of increased muscle strength. The added advantage no deleterious effects when using umbilical cord tissue derived stem cells is indicative of the safety of this treatment modality.

Stem cell therapy new hope to cure muscular Dystrophy: Dr Nandini

Somashekhar, a medical store owner from Mumbai ,who was unable to stand on his feet and walk since past 15 years due to Becker’s Muscular Dystrophy disorder could now carry on his daily routine without any problem, thanks to Mumbai based NeuroGen, Brain and Spine Institute. Somashekhar is the recipient of a stem cell based therapy, which helped him recover within a span of six months. Dr NandiniGokulchandran, deputy director and head of medical services of NeuroGen said stem cell therapy is new hope for patients suffering from so far incurable debilitating disease called Muscular Dystrophy, disorders connected to brain and muscles.

Ryan Benton, a MD patient recently celebrated his 30th birthday thanks to an allogenic adult stem cell transplantation he has undergone. This was the first ever documented case of a MD patient who has lived beyond the normal life expectancy for patients with MD. Due to the restrictions in the US, Ryan had to take several trips to panama to undergo the experimental stem cell therapy. The FDA finally realized the importance of using stem cells for treating MD and granted approval for Ryan to undergo the treatment in the US on a regular basis which led to a more effective reversion of the disease’s progression.

 

Chances for Muscle Regeneration Improved with Pre-Transplant Cell Treatment

Dr. Shin’ichi Takeda’s research group at the Department of Molecular Therapy, National Institute of Neuroscience, National Center of Neurology and Psychiatry in Kodaira, Japan has successfully shown that muscle stem cells, treated with leukemia inhibitory factor (LIF) are better at forming new muscle fibers when transplanted into the body. Satellite stem cells, found in the muscle have been studied as a therapeutic approach for many years to induce the production of new muscle fibers in people with muscle disease such as Duchenne muscular dystrophy. But studies on the transplantation efficiency of these satellite stem cells in vitro have not yielded positive results. But now, pre-treatment of the satellite cells with LIF, a cytokine could help maintain the undifferentiated state of these cells. According to Dr. Shin’ichi Takeda,“This research enables us to get one step closer to the optimal culture conditions for muscle stem cells”.
