摘要: 目的探讨神经干细胞分离、培养及鉴定的方法,并了解其生物学特性。方法分离大鼠胎鼠腹侧中脑组织,加入丝裂原bFGF进行克隆密度细胞培养。用免疫细胞化学方法进行神经干细胞及其分化细胞的鉴定。结果培养的神经干细胞具备神经干细胞的基本特性,以对称和不对称分裂方式增殖形成神经球,并分化为神经元、神经胶质细胞、少突胶质细胞。结论成功建立了神经干细胞的分离培养方法。

Abstract: ObjectiveTo establish a method of isolation and culture of neural stem cells(NSCs). MethodsTissues of ventral midbrain were isolated from a rat embryo,and the NSCs were cultured stimulated with basic fibroblast growth factor(bFGF)in vitro.The cells were identified by immunocytochemistry.ResultsNSCs proliferated into neurosphere in symmetric and non-symmetric cleavage ways,and differentiated into neuron, astroglia and oligodendrosyte. ConclusionsThe method has been established to isolate and culture the neural stem cells.

Key words: ventral midbrain of rat embryo, neural stem cell, isolation, culture
