Safety and Efficacy of Umbilical Cord Mesenchymal Stem Cell Therapy for Patients With Progressive Multiple Sclerosis and Neuromyelitis Optica

Multiple sclerosis (MS) has been classically regarded as a chronic inflammatory autoimmune demyelinating disease of the central nervous system, along with a considerable pathological heterogeneity. Neuromyelitis optica (NMO) is a severe inflammatory, demyelinating disease, and its clinical characteristics include recurrent optic neuritis and longitudinally extensive transverse myelitis. Current therapies provide only modest control of progressive Multiple Sclerosis and Neuromyelitis Optica.Stem cell therapy might open a light horizon in approaching to an efficient treatment in progressive MS and NMO. In this study, the safety and efficacy of Human Umbilical Cord Mesenchymal Stem Cells transplantation will be evaluated in patients with progressive MS and NMO.
