摘要
为观察食蟹猴骨髓基质干细胞 (BMSC)体外培养及诱导分化情况 ,分离食蟹猴的BMSC ,以神经干细胞培养液和分化诱导因子进行体外培养和诱导分化。结果发现 ,分离得到的食蟹猴BMSC能在体外培养中增殖、分化 ,这些具有克隆能力的BMSC能表达神经干细胞特异性抗原Nestin,并能进一步诱导分化出胶质细胞样细胞和神经元样细胞 ,免疫细胞化学检测可见有GFAP和NSE抗原表达。提示灵长类BMSC是多分化潜能细胞 ,具有较强的自我更新和多分化能力 ,在适当的诱导分化条件下可形成具有神经系细胞 (神经元和神经胶质细胞)特征的细胞 ;
To observe the growth, expansion and differentiation of the cultured bone marrow stroma cell (BMSC) from Macaca Lrus, BMSC isolated from adult Macaca Lrus were cultured with the culture medium confected by ourselves and were induced with some cytokines such as LIF and bFGF. The results showed that the BMSC could proliferate and generate Nestin positive clones when they were cultured in vitro. After subculture, these cells could grow rapidly and differentiated into neuron like cells and astrocyte like cells further, which expressed GFAP or NSE antigen respectively. Therefore, these BMSC possess renewal and differentiation abilities. On the other hand, the culture method we used in this experiment is suitable for culture of BMSC in vitro. The BMSC might be used as the seed cells of the neural stem cells.
