Result: Schwann-like cells disperse in the hole of nerve graft at oneweek under Scanning Electronic Microscope, the processes of thesatellite-like cells adhere to the wall of graft.There was no statisticaldifference of activity of cells in both group(P＞0.05) using MTT. At 12weeks,the result of appearance, histology and TEM were similar, therewere no statistical difference in SFI%, NEP and quantitative analysis ofrecovery rate of myelinated fiber populations, diameter of myelinatedfiber and thickness of myelin sheat.

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.

The culture was treated with lutein of different concentrations 10^(-8mol/L、10^(-7)mol/L、10^(-6)mol/L, respectively. The culture cells were fixed and were stained for tartate-resistant acidic phosphatase after 7d. The formation of osteoclasts was quantified by counting the number of TRAP(superscript +) multinuclear cells. The percentage of bone resorbed surface, TRAP activity and the expression of receptor activator of NF-KB mRNA were analysed. The appearance of reduced mice osteoclasts was typical.
