[Inductive effect of deprenyl and dimethyl sulfoxide on proliferation and survival of the mesenchymal stem cells]

Research have been focused on the applying the chemical inducer for transdifferentiation the adult BMSCs into neural cell. So that, at the first should investigate the toxcity effect of the chemical inducer on the induced cells. Plasticity and easy accessibility of bone marrow mesenchymal stem cells is a unique charactristic for treatment of neural disorderies. This study was desgined to determine the inductive effect of Deprenyl and Dimethyl sulfoxide on proliferation and survival of the mesenchymal stem cells. In this experimental study, BMSCs isolated from the adult rat bone marrow and cultured in alpha MEM containing 10% FBS. Cell identity for surface antigens was performed in third passage by immunocytochemistry and multipotancy capacity of BMSCs was done by BMSC differentiation into adipocytes and osteocytes. The cells were exposed to chemical agents [a: the alpha MEM medium supplemented with 2% DMSO, b: the alpha MEM medium supplemented with 10[-8]M Deprenyl] for 24 hours and then transferred to alpha MEM containing 10% FBS cell survival and proliferation was evaluated after the 24, 48, 72 and 96 houres by MTT [3-[4-5-Dimethylthiazolyl-2-y1]-2,5-diphenyltetrazolium romid] test. Data were analyzed using SPSS-16, One-Way ANOVA and Tukey tests. In addition to expression the surface antigens and adipogenic and osteogenic differentiation by BMSCs, MTT test results showed that proliferation and survival of induced-deprenyl and DMSO cells within 48, 72 and 96 hours after the induction was increased significantly than negative control group. Deprenyl increases survival and cell proliferation compared to Dimethyl Sulfoxide. It can be used as cell inducer
