成体骨髓细胞向神经细胞转化的特征

体外诱导骨髓基质干细胞分化为神经细胞已经成为神经科学研究的热点之一.目前在某些实验条件下,组织特异性的干细胞在组织和器官中能衍生为各种细胞谱系.已经有撤道称骨髓基质细胞能衍生为骨骼细胞、胃贲门细胞、椭圆形肝细胞、神经胶质细胞和神经元样细胞.因此,通过资料研究分析出生后的骨髓细胞被诱导增殖进而分化为神经胶质细胞和神经元细胞,对其转化的特征作出探讨.

Transformation from adult bone marrow cells into neural cells

In vitro differentiation of bone marrow stromal stem cells (BMSCs) into neural cells has been a hot study in neuroscience. Presently, under some experimental conditions, tissue-specific stem cells have been shown to give rise to cell lineages not normally found in the organ or tissue of residence. BMSCs have been reported to generate skeletal cells, gastric cardiac cells, oval hepatocytes, as well as glia and neuron-like cells. Cells from postnatal bone marrow were induced to proliferate and differentiate into gila and neurons. The present study explored the characteristics of its transformation.
