The adipose derived stem cells of inbreds train of rat wereinduced to differentiate into schwann-like cells and the cells were injectedinto the acellular nerve allograff.The proliferation or adhersion of these cells on the graft were observed by inverted microscope or ScanningElectronic Microscope. Activity of cells were detected using MTT. 10mmnerve gap of inbreds train of rats in two group were bridged by tissue-engineered peripheral nerve or autogenous nerve, the effect wereappraised by naked eye, recovery rate of sciatic function index,nerve-electrophysiological, histology, Transmission ElectronMicroscopy and quantitative analysis of recovery rate of myelinated fiberpopulations,diameter of myelinated fiber and thickness of myelin sheat.

按照前述方法培养并诱导近交系大鼠脂肪干细胞向类Sehwann分化，将诱导分化的脂肪干细胞悬液注入已制备的去细胞同种异体神经支架管中，倒置显微镜观察细胞生长情况；扫描电镜下观察细胞在材料上附着情况；四唑盐比色试验测定细胞活性；取两组近交系大鼠，分别用组织工程化神经和自体神经桥接10mm神经缺损，通过大体观察、坐骨神经功能指数恢复率的测定、神经电生理的测定、组织学光镜观察、透射电镜观察、再生有髓神经纤维计数恢复率、神经纤维直径恢复率、髓鞘厚度恢复率的测定等指标评价实验效果。
