Expanded MSCs were induced to differentiate into nerve cells withthree different treatment protocol in the prensent study . On the following day, the medium was replaced with preinduction medium consisting of DMEM, 20% FCS, and 10 ng/ml basic fibroblast growth factor. After 24 h, the preinduction medium was removed, the cells were washed twice with PBS, and neuronal induction medium containing DMEM supplemented with 2% DMSO and200 m bu-tylated hydroxyanisole was added. In later experiments, we used DMEM with 5 mM p - mercaptoethanol or sulfo - glycerine as an alternative neuronal induction medium for the same incubation.
