神经干细胞(neural stem cells,NSCs)具有自我更新、自我增殖和多向分化潜能,它的发现为人们深入研究中枢神经系统的发育、分化以及探索治疗神经系统疾病的新途径开辟了新的思路[1]。研究证实,哺乳动物的胚胎和成体内均存在NSCs。在胚胎时期,神经干细胞存在于大脑皮质、纹状体? Neural stem cells (NSCs) have the potential of self-renewal, self-proliferation and multidirectional differentiation, and their discovery has opened up new ideas for people to further study the development and differentiation of the central nervous system and explore new ways to treat diseases of the nervous system [ 1]. Studies have shown that both mammalian embryos and adult NSCs exist. In the embryonic period, neural stem cells exist in the cerebral cortex, striatum?
