【Abstract】 Objective To explore the means of transdifferentiation of bone marroesenchymal stem cells(BMSC) of adult rat to neuronlike cells in vitro. Methods BMSCs adult rats using gradient cent rifugation and subculture differentiation munocytochemistry analysis a examination neuron specific enolase(NSE)、neurofilament protein (NF) and glial fibrillary acidic protein (GFAP) and floetry analysis examination ed inductivity. Results The BMSC could be transdifferentiated to neuronlike cells arroal stem cells; Induction differentiation; Neuronlike cells
