| 摘 要： | 利用无血清培养和细胞克隆技术从孕鼠(14d)胚胎中分离出神经干细胞，并进行传代培养，采用免疫细胞化学技术检测神经巢蛋白和成熟脑细胞特异性抗原神经元特异性烯醇化酶(neuron specific enolase，NSE)、胶质纤维酸性蛋白(glial fibrillary acidic protein，GFAP)的表达，同时采用H-E染色法鉴定神经细胞类型。证实从大鼠胚胎大脑皮质分离出的细胞具有连续的克隆能力，并表达神经巢蛋白，分化的细胞表达神经元和神经胶质细胞的特异性抗原，为中枢神经系统的干细胞。 |

| Abstract: | This study is to set up a method for separating,culturing and identifying neural stem cells from cortex in rat embryo,observing their characteristics of multipotentiality and differentiation in vitro. By using serum-free cell culturing and clone technology,the stem cells were isolated,cultured and passaged from cortex in 14-day old rat embryo. The expression of Nestin antigen of brain cells were investigated by immunocytochemistry and H-E staining. It proved that cells separated from cortex in rat embryo possessed the potential to form clones and express nestin special antigen,the differentiated cells could express special antigen of neurons,astrocytes,and oligodendrocytes,they were stem cells of central nervous system. |
