| Abstract: | Objective: To investigate the mechanism of high proportion of neurons generated from new born rats mesencephalic neural stem cells (NSCs) induced by bone marrow stromal cells (BMSCs) of adult rats. Methods:The differentiation of NSCs was observed under microscope when NSCs was cultured alone or cocultured with BMSCs. The identity of neurons was confirmed by immunofluorescence stain. Results:(1)The high proportion of neurons generated from NSCs was resulted from the differentiation action induced by BMSCs. (2)BMSCs enhanced the survival of neurons generated from NSCs. Conclusion:BMSCs can provide signals required for differentiation of NSCs into neurons and for survival of neurons. |
