Human embryonic stem cells the bodys powerful master cells might be useful for treating multiple sclerosis, researchers reported Thursday. A team has used cells taken from frozen human embryos and transformed them into a type of cell that scientists have hoped might help treat patients with MS, a debilitating nerve disease. Mice with an induced version of MS that paralyzed them were able to walk freely after the treatment, the teams at Advanced Cell Technology and ImStem Biotechnology in Farmington, Connecticut, reported. The cells appeared to travel to the damaged tissues in the mice, toning down the mistaken immune system response that strips the fatty protective layer off of nerve calls. Its that damage that causes symptoms ranging from tremors and loss of balance to blurry vision and paralysis. These embryonic stem cells were carefully nurtured to make them form a type of immature cell called a mesenchymal stem cell. These cells worked better to treat the mice than naturally developed mesenchymal stem cells taken directly from bone marrow, the team wrote in the journal Stem Cell Reports, published by the International Society for Stem Cell Research.

Farmington, CT (PRWEB) June 05, 2014 ImStem Biotechnology, Inc. (ImStem) announced today it has successfully treated an animal model of multiple sclerosis (MS) using human embryonic stem cells (hESC) derived mesenchymal stem cells (MSCs), called hES-MSCs. MS is a chronic neuroinflammatory disease with no cure. Most current MS therapies offer only palliative relief without repairing damaged nerve cells. Adult tissues such as bone marrow derived MSCs (BM-MSCs) may reduce neuroinflammation and promote nerve cell regeneration in MS, which are currently being tested in MS clinical trials. However, the application of adult-tissue derived MSCs has significant limitations since these cells must be obtained from a limited number of healthy donors, constraining the availability of this treatment and also resulting in variations in treatment quality. Now researchers from ImStem, in collaboration with University of Connecticut Health Center (UCHC) and Advanced Cell Technology, Inc., demonstrates that hES-MSCs, which have unlimited stable supply, significantly reduce the disease severity in a mouse model of MS. They also found that hES-MSCs are more effective in treating animal model of MS than MSCs from bone marrow of adult human donors (BM-MSC).
