Abstract

Multiple Sclerosis (MS) is an autoimmune inflammatory demyelinating disease of the central nervous system. The aim of this study was to investigate the neuroprotective effects of transplanted human umbilical cord blood mesenchymal stromal cells (UCB-MSC) derived neural progenitor cell (MDNPC) in EAE, an experimental model of MS. To initiate neuronal differentiation of UCB-MSCs, the pre-induction medium was removed and replaced with induction media containing retinoic acid, b FGF, h EGF, NGF, IBMX and ascorbic acid for one week. The expression of neural genes was examined in comparison to control group by real-time PCR assay. Then, experimental autoimmune encephalitis (EAE) was induced using myelin oligodendrocyte glycoprotein (MOG, 35-55 peptides) in 24 C57BL/6 mice. After induction, the mice were divided in four groups (n=6) as follows: healthy, PBS, UCB-MSCs and MDNPC, respectively. At the end of the study, disease status in all the groups was analyzed using hematoxylin-eosin (H&E) staining of brain sections. We found that UCB-MSCs exhibit neuronal differentiation potential in vitro and transplanted MDNPC lowered clinical score and reduced CNS leukocyte infiltration compared to untreated mice. Our results showed that MDNPC from UCB may be a proper candidate for regenerative therapy in MS and other neurodegenerative diseases.
