胚胎缺氧可导致胎儿大脑严重的损伤,目前仍为神经系统残疾的主要原因之一。传统认为神经系统受损后一般不具修复功能,而神经干细胞(neural stem cell NSC)的发现改变了这一观点。人们在成体和胚胎大脑中均发现有神经干细胞的存在,其激活后能产生神经元和胶质细胞,这对疾病的恢 Hypoxia in embryos can lead to severe brain damage in the fetus and remains one of the major causes of neurological disability. Traditionally, there is generally no repair function after the nervous system is damaged, and the discovery of neural stem cell NSC changes this view. People in the adult and embryonic brain are found in the presence of neural stem cells, its activation can produce neurons and glial cells, which restore the disease
