简介：客观：为了探索可行性构造遗传工程人，神经干细胞(hNSCs)由lentivirus调停了多表示基因以便为针的绳索损害(SCI)的进一步的研究提供接枝来源。方法：从人的流产胎的大脑外皮的人的神经干细胞被孤立并且有教养，然后，基因被lentivirus修改两个都表示绿荧光蛋白质(GFP)和老鼠neurotrophin-3(NT-3)；转基因的表示被荧光显微镜，胎儿的老鼠的背面的根中心和槽污点的方法检测。结果：遗传工程hNSCs成功地被构造。所有在荧光显微镜下面表示了明亮绿的荧光的遗传工程hNSCs被观察。转基因的hNSCs的调节媒介能导致从背面的根中心(DRG)挥舞长出的神经突。遗传工程hNSCs表示了高级NT-3which能被使用槽污点检测。结论：遗传工程hNSCs调停了bylentivirus能被构造多成功地表示基因。
