一、神经干细胞的来源和分裂神经干细胞是指具有分化为神经元、星形胶质细胞、少突胶质细胞的能力 ,能自我更新并足以提供大量脑组织细胞的细胞。Morshead等人[1] 证明了室管膜细胞与神经球细胞有关 ,他们发现培养去除了室管膜的脑组织 ,就得不到神经球 ,可见神经干细胞来源于 I. The Origin and Division of Neural Stem Cells Neural stem cells are cells that have the ability to differentiate into neurons, astrocytes, oligodendrocytes, self-renewing, and enough to provide a large number of brain tissue cells. Morshead et al [1] proved ependymal cells and neurosphere cells, they found that the culture of edematous brain tissue removed, we can not get the neurospheres, neural stem cells can be seen from
