Fingolimod increases oligodendrocytes markers expression in epidermal neural crest stem cells.

Fingolimod increases oligodendrocytes markers expression in epidermal neural crest stem cells. Eur J Pharmacol. 2020 Aug 26;:173502 Authors: Pournajaf S, Valian N, Shalmani LM, Khodabakhsh P, Jorjani M, Dargahi L Abstract Epidermal neural crest stem cells (EPI-NCSCs) are propitious candidates for cell replacement therapy and supplying neurotrophic factors in the neurological disorders. Considering the potential remyelinating and regenerative effects of fingolimod. in this study, we evaluated its effects on EPI-NCSCs viability and the expression of neurotrophic and oligodendrocyte differentiation factors. EPI-NCSCs, extracted from the bulge of rat hair follicles, were characterized and treated with fingolimod (0, 50, 100, 200, 400, 600, 1000, and 5000 nM). The cell viability was evaluated by MTT assay at 6, 24 and 72 h. The expression of neurotrophic and differentiation factors in the cells treated with 100 and 400 nM fingolimod were measured at 24 and 120 h. Fingolimod at 50-600 nM increased the cells viability after 6 h, with no change at the higher concentrations. The highest concentration (5000 nM) induced toxicity at 24 and 72 h. NGF and GDNF genes expression were decreased at 120 h, but on the contrary, brain derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3) were increased by both concentrations at both time points. Oligodendrocyte markers including platelet-derived growth factor receptor A (PDGFRα),...
