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.
