摘要:  神经干细胞提取及体外培养的方法有多种, 但采用不同方法所得到的神经干细胞的活力与稳定性均不同。通过对提取和体外培养SD胎鼠大脑皮质神经干细胞的过程进行思考, 总结出神经干细胞的提取步骤、 提取要点、 培养基的选择依据、 接种密度的选择、 培养方法、 换液方法、 传代时机、 传代方法, 最终获得大量活力和稳定性均较高的神经干细胞, 并将其应用于相关方面的基础研究。

关键词: 干细胞, 神经元, 培养基, 连续传代, 细胞提取, 悬浮培养法

Abstract:  There are many ways to extract and culture neural stem cells in vitro, but the viability and stability of neural stem cells obtained by different methods are different. By thinking about the process of extracting and culturing neural stem cells in vitro from the cerebral cortex of SD fetal rats, we summarized extraction steps, the main points of extraction, the selection basis of culture medium, selection of inoculation density, cultural method, methods of solution changing, passage time and passage methods. At last a large number of neural stem cells with high vitality and stability have been obtained and applied to the basic research of neural stem cells.

Key words: stem cells, neurons, culture media, serial passage, cell extraction, suspension culture method
