Results Compared with normal group and sham operated control groups, BrdU positive and Nestin positive cells were increased in the hippocampus, dentate subgranular zone and subependymal zone in operated groups after 24 hours of reperfusion of omni-cerebral ischemia.

结果 脑缺血再灌流24 h后，海马、齿状回和室管膜下区的BrdU阳性细胞和Nestin阳性细胞增多，7～10 d达到高峰，术后20 d仍有表达；在室管膜下区，BrdU阳性细胞和Nestin 阳性细胞有向皮质、海马迁移的现象。

In fact, cells with NSCs-like properties are likely to occur throughout the adult CNS, but they are able to give rise to neurons in only a few restricted areas in vivo, i.e., the subventricular zone in the wall of the lateral ventricle and the subgranular zone of the hippocampal dentate gyrus. Very poor regenerative capability of the adult mammalian CNS could be explained as follows: first, theneuronal differentiation of endogenous NSCs may be inhibited by microenvironmental factors present in most areas of the adult CNS.

成年哺乳动物中枢神经系统可怜的再生能力可能主要归结于两方面的原因：第一，成年动物中枢神经系统内的大多数区域存在一些特殊的微环境因素，它们抑制了内源性神经干细胞向神经元方向的分化；第二，内源性神经干细胞的数量太少，不足以形成有效的自我修复。

Results compared with normal group and sham operated control groups, brdu positive and nestin positive cells were increased in the hippocampus, dentate subgranular zone and subependymal zone in operated groups after 24 hours of reperfusion of omni-cerebral ischemia. the expression of brdu and nestin reached a peak 7-10 days after the operation, and could still be detected 20 days after the operation. the migration of brdu positive and nestin positive cells to the cerebral cortex and hippocampus was observed in subependymal region.

结果 脑缺血再灌流24 h后，海马、齿状回和室管膜下区的brdu阳性细胞和nestin阳性细胞增多，7～10 d达到高峰，术后20 d仍有表达；在室管膜下区，brdu阳性细胞和nestin 阳性细胞有向皮质、海马迁移的现象。
