Abstract:
Objective To observe the growth and differentiation of the cultured mouse bone marrow stromal cells in vitro into neural like cells. Methods Bone marrow stromal cells (BMSCs) isolated from mice were cultured according to the routine method, and induced to differentiate by basic fibroblast growth factor b (bFGF), retinoic acid (RA), nerve growth factor (NGF), and dimethylsulfoxide (DMSO). Expressions of neural microfilament protein (NF 200), glial fibrillary acidic protein (GFAP), and fibronectin at 72 h after inductin were determined by immunoflurenscence and immunocytochemicalmethod. Results At 72 h after inductin, neural like changes were found in BMSCs. Immunohistochemical stain showed that 60% BMSCs differentiated into NF 200 positive cells, and about 50% BMSCs into GFAP positive cells. Fibronectin expression was significantly lower as compared with that in the control group. Conclusion Combined action of RA, bFGF, NGF, and DMSO can induce BMSCs to differentiate into neural like cells in vitro .
