Part three: An experiment study on the repair of peripheral nerve injury by NT-3 gene modified neural stem cells objective To investigate the effective treatment of peripheral nerve injury with NT-3 gene modified neural stem cells, to explore the feasibility of the treatment by means of gene transfection Methods 54 SD rats were divided evenly into 3 groups. The sciatic nerve transected model were made and sutured end to end with epineurium. The neural stem cell without NT-3 gene or with NT-3 gene modified were injected into triceps muscle one time a week, saline injected as control group. The nerve trunks of stomas and triceps muscle were acted as specimen three weeks、six weeks and nine weeks after operation.

About 4 days post amputation, cells in some areas in the out epidermis and inner parietal peritoneum near the end of the stump are induced by injury to dedifferentiate into stem cells and then proliferate forming stem-cell masses, which then invaginate into the interior dermis. The dermal cells are then induced by those invaginating stem-cell masses to dedifferentiate.

UV-B radiation induced significant changes in the chemical composition of root, stem, and leaf. Under UV-B radiation, the soluble protein, lignin, and fat contents in leaf, lignin content in root, and cellulose and lignin contents in stem were increased, while the starch content in leaf and the soluble sugar, starch, and fat contents in stem were decreased significantly (P.05), compared with the control.

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.
