According to a study by researchers at Cleveland's Case Western Reserve University School of Medicine, pre-existing inflammatory diseases affecting the central nervous system make mesenchymal stem cells less effective in treating multiple sclerosis. The study notes that MSCs potentially produce several signaling proteins that can regulate immune system responses as well as help tissue regenerate. Preclinical studies have shown that this can reduce brain inflammation while improving neural repair in animal models of experimental autoimmune encephalomyelitis -- an animal version of MS that is often used in laboratory studies, since it resembles the inflammation and neuronal damage seen in MS patients. Given the need for effective new MS therapies, the results will help MSCs to advance to human clinical trials. So far, results have reported good safety data, though such therapies have failed to demonstrate therapeutic efficacy. Most such trials so far have used stem cells collected from the patient, a process known as autologous transplantation — yet this may explain why MSCs have not been effective. It's possible that pre-existing neurological conditions may alter stem cells' responsiveness as well as their therapeutic activity. To see whether that is in fact the case, team members collected stem cells from the bone marrow of EAE mice. But these stem cells were unable to improve EAE symptoms, whereas stem cells collected from healthy mice retained all their therapeutic potential and improved EAE symptoms. A more detailed analysis showed that the MSCs derived from EAE animals had different features than their healthy counterparts. In addition, the team confirmed that MSCs collected from MS patients were also less effective in treating EAE animals, compared to MSCs from healthy controls. Indeed, these MSCs from patients produced pro-inflammatory signals instead of the protective anti-inflammatory ones. “Diseases like EAE and MS diminish the therapeutic functionality of bone marrow MSCs, prompting re- evaluation about the ongoing use of autologous MSCs as a treatment for MS,” the team wrote, adding that its study supports the advancement of MSC therapy from donors rather than autologous MSC therapy to treat MS while raising "important concerns over the efficacy of using autologous bone marrow MSCs in clinical trials."

Researchers at The Salk Institute have developed a way to grow vital brain cells called astrocytes from stem cells, a potential breakthrough for basic and clinical research into several diseases, including multiple sclerosis (MS). The study “Differentiation of Inflammation-responsive Astrocytes from Glial Progenitors Generated from Human Induced Pluripotent…
The recent annual meeting of the Consortium of Multiple Sclerosis Centers (CMSC) brought researchers and healthcare professionals to New Orleans to discuss advances — and obstacles to advances — in multiple sclerosis (MS) research. Clinical trials, preclinical studies, basic research, and health interventions were among the May meeting’s focus. Multiple Sclerosis News…
Researchers from the New York Stem Cell Foundation (NYSCF) have developed a method to produce brain immune cells, called microglia, from human stem cells. That can help scientists uncover biological mechanisms involved in multiple sclerosis (MS) and other neurological conditions. “NYSCF’s mission is to bring cures to patients faster,” Susan L.
The National Multiple Sclerosis Society is pumping $17 million into 43 research projects that represent almost half of its $40-million research funding commitment in 2017. Among the projects are trials evaluating intermittent fasting as a way to harness inflammation and stem cell research. A growing number of studies indicate that stem cells can slow…
Brain stem cells from primary progressive multiple sclerosis (PPMS) patients lack the ability to repair brain damage and to trigger the maturation of protective myelin-producing cells, a surprising study with far-reaching implications indicates. The study also showed that stem cells from individual patients reacted differently to compounds developed to trigger…
The United States has granted a patent to Kadimastem’s stem cell-based technology for treating multiple sclerosis (MS) and other diseases of the nervous system. The patent involves the technology the company used to produce supporting cells in the central nervous system derived from human stem cells, including myelin-producing cells. The United…
Regulatory T-cells in the central nervous system trigger the maturation of stem cells that increase the production of myelin at injured neurons — a discovery that places the idea of regeneration in multiple sclerosis (MS) in a whole new light. Myelin is a substance essential to the functioning of the…
The 21st Century Cures Act, recently signed into law by President Barack Obama, includes provisions that aim to speed up the process by which the U.S. Food and Drug Administration (FDA) reviews stem cell treatments for patients with degenerative diseases, such as multiple sclerosis, rheumatoid arthritis, and Parkinson’s disease. This act also…
Researchers have found neural stem cells (immature cells that can become neurons) in the meninges of the brain, a three-layer structure that protects the nervous system, according to results of a new study. The discovery of this pool of stem cells in the adult brain opens new possibilities for the…
Damaging immune system defects seen in patients with multiple sclerosis (MS) can be repaired using a simple stem cell approach, according to a new study by researchers in China and the U.S. The study, “Umbilical Cord-Derived Mesenchymal Stem Cells Reversed The Suppressive Deficiency Of T Regulatory Cells From Peripheral Blood Of…
What should be done about stem cell treatments? Are stem cells safe? Do they work? Do stem cell clinics need more regulation, or less? With some studies reporting encouraging results from using stem cells to treat a number of diseases, including multiple sclerosis, the number of clinics around…
