Preferable treatment for MS found in allogenic bone marrow stem cells
Date:12/18/2013

Putnam Valley, NY. (Dec. 18, 2013) Multiple sclerosis (MS), an inflammatory autoimmune disease affecting more than one million people worldwide, is caused by an immune reaction to myelin proteins, the proteins that help form the myelin insulating substance around nerves. Demyelination and MS are a consequence of this immune reaction. Bone marrow mesenchymal stem cells (MSCs) have been considered as an important source for cell therapy for autoimmune diseases such as MS because of their immunosuppressive properties.

Now, a research team in Brazil has compared MSCs isolated from MS patients and from healthy donors to determine if the MSCs from MS patients are normal or defective. The study will be published in a future issue of Cell Transplantation but is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/ct/pre-prints/content-ct1131.

"The ability of MSCs to modulate the immune response suggests a possible role of these cells in tolerance induction in patients with autoimmune diseases, and also supports the rationale for MSC application in the treatment of MS," said study corresponding author Dr. Gislane Lelis Vilela de Oliveira of the Center for Cell-Based Research at the University of Sao Paulo. "We found that MS patient-derived MSCs present higher senescence, or biological aging, and decreased expression of important immune system markers as well as a different transcriptional profile when compared to their healthy counterparts."

The researchers suggested that further clinical studies should be conducted using transplanted allogenic (other-donated) MSCs derived from healthy donors to determine if the MSCs have a therapeutic effect over transplanted autologous (self-donated) MSCs from patients.

"Several reports have shown that bone marrow-derived MSCs are able to modulate innate
