增殖体

As a kind of stem cell of mature body, umbilical cord blood mesenchymal stem cell has multiple differentiate directions, ability of active proliferation, high efficiency of transfection and expression to exogenous gene, promote hematopoiesis, isolate and culture easily in vitro, which arouse more and more interesting to researchers both from national and international.

作为成体干细胞中的一种，脐血间质干细胞具有良好的多向分化潜能、活跃的增殖特性、对外源基因的高效转染表达能力以及促进造血、在体外较易分离、培养等特性，日益引起国内外研究者的浓厚兴趣。

apoptosis and proliferation in the rat olfactory bulb reduces gradually from embryo to adult.

Objective To study the effects of ischemia-reperfusion-like condition on intracellular Ca^2＋, activity and proliferation of neural stem cells of fetal mouse corpus striatum cultured in vitro .

目的观察类缺血再灌注损伤对体外培养的胚胎小鼠纹状体神经干细胞活性、胞内Ca^2＋浓度以及增殖的影响。

Neural stem cells, defined by Reynols 1992, which were derived from the adult mice corpus striatum firstly, can uninterruptly proliferate and multidifferentiate in vitro and in vivo.

神经干细胞(neural stem cells，NSCs)是干细胞的一种，Reynolds等于1992年首先从成年小鼠脑纹状体分离出能在体外不断分裂增殖、具有多种分化潜能的细胞群，并正式提出了神经干细胞的概念。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
