Abstract: Objective To research the effects of neural stem cells (NSCs) transplantation on the neurological function improvement and neural survive and axonal regeneration in traumatic rat brain. Methods NSCs were cultured in vitro, labeled with hochest and transplanted into rat brain injured area by weight-dropping. Neurological severity scores(NSS) tested the functions at the 0,3,7,14 day post-injury. Immunofluorescence was used to detect the expressions of NeuN cells and GAP-43. Results There was significant difference in NSS between NSCs transplantion group and brain injury group(4.38 ±0.74 vs 5.50 ± 1.07, P＜0.01) at 7th day. There were a significant increase in neural number (51.46 ± 3. 303 vs 42.83 ± 5. 401, P ＜ 0.01 ) ), and GAP-positive axons ( 13.3 ± 1.7 vs 8.7 ± 1.1, P＜0.01 ) in NSCs transplantion group than in control group. Conclusion NSCs have an effects on the neurological improvement in brain injured rat. This may be associated to the increase in number of the neurons and local axons.
