Stem Cell Treatment for Multiple Sclerosis is one of the best treatments. Multiple Sclerosis is an autoimmune disease that affects our brain & spinal cord. In this disease the immune system attacks the protective sheath (myelin) covering nerve fibers in MS, causing problems with brain-to-body communication. t is possible that stem cell therapy can have a positive impact on patients with Multiple Sclerosis. Multiple sclerosis patients may benefit greatly from mesenchymal stem cells since they reduce inflammation and modulate the immune system.
