RESUMO
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.
