Objective To investigate the differentiating effects of salvia miltiorrhiza on bone marrow stromal cells. Methods Salvia miltiorrhiza was adapted to induce the cells differentiating. The undifferentiated cells and differentiated cells were identified with immunocytochemistry. Results Salvia miltiorrhiza induced the stem cells to express nestin, musashi 1,characteristics of neuronal precursor stem cells at early stage of differentiation, later they exhibited a neuronal phenotype, expressing neuron specif...
