A new study has shown that a protocol for treating Multiple Sclerosis with stem cells is safe. According to the researchers, the potential for using stem cells in Multiple Sclerosis therapy warrants further investigation. The results of the study were published in the Journal of Translational Medicine.
Stem cells – and specifically, mesenchymal stem cells, have been increasingly used in the treatment of immune and inflammatory conditions. Based on the success that has been seen in these areas, scientists reasoned that mesenchymal stem cells may also represent a useful approach to treat Multiple Sclerosis, a neurological disease that involves the abnormal attack by the immune system on the myelin sheath that insulates nerves and allows nerve cells to communicate effectively and efficiently with one another.
To test this idea, the scientists used umbilical cord mesenchymal stem cells in 20 Multiple Sclerosis patients. The patients were given intravenous injections of the stem cells each day for seven days. The researchers evaluated the patients – with both neurological testing and nervous system imaging – at baseline, one month after treatment, and one year after treatment. The researchers found that the stem cell treatment improved neurological scores in patients and that lesions in the brain and cervical spinal cord were inactive one year after the stem cell injections. There were no serious adverse side effects associated with the treatment.
Based on these findings, it is possible that stem cells will provide a useful treatment option for those with Multiple Sclerosis. With more research, we will better understand exactly how stem cells can be used to help this population of patients.
