在整个脊椎动物进化过程中,Sox 2标志着神经系统从其最早的发育阶段开始发育,并且在其中,最未分化的前体细胞,包括干细胞。最近的基因靶向研究调查了Sox 2在两个神经系统中的功能:发育中的眼睛和大脑。这些研究揭示了Sox 2在维持神经干细胞中的需求,以及在特定神经元亚型分化中的下游作用。在这两个系统中,Sox 2的作用是显着的剂量依赖性,下游靶基因的研究开始揭示Sox 2功能的机制。(C)2009年由Elsevier Ltd.出版
Throughout vertebrate evolution, Sox2 marks the developing nervous system from its earliest developmental stages and, therein, the most undifferentiated precursor cells, including stem cells. Recent gene targeting studies investigated the function of Sox2 in two neuronal systems: the developing eye and brain. These studies uncovered a requirement for Sox2 in the maintenance of neural stem cells, as well as a downstream role in the differentiation of specific neuron sub-types. In both systems, Sox2 action is markedly dose-dependent, and downstream-target gene studies are beginning to reveal the mechanisms of Sox2 function. (C) 2009 Published by Elsevier Ltd.
