Abstract

Abstract: Objective To observe the effects of neurotrophin 3 (NT3)-chitosan on motor function, and proliferation and differentiation of the neural stem cells (NSCs) in the injury area and subventricular zone (SVZ) in rats with motor cortex injury. Methods Sixty-five Wistar rats were divided into control group (n=7), injury group (n=29) and NT3-chitosan group (n=29). The motor cortex was aspirated and removed as cerebral injury model. NT3-chitosan was immediately implanted into the injured area after operation, and the control group received no intervention. Pellet reaching test was performed to detect the recovery of the forelimb function, HE staining was used to observe the lesion cavity size, and immunofluorescence staining was used to observe the proliferation and differentiation of NSCs 3 days, 7 days, 14 days, 1 month, 2 months and 3 months after operation. Results The grasp success rate was higher (F>6.00, P≤0.05), and the lesion cavity size was significantly smaller (F>629.5, P<0.001) in the NT3-chitosan group than in the injury group. In the NSCs differentiation experiment, the number of BrdU cells at all the time points was significantly higher in the NT3-chitosan group than in the injury group (F>171.43, P<0.001). In the NSCs proliferation experiment, the number of BrdU positive cells was still significantly higher in the NT3-chitosan group than in the control group and in the injury group (F>155.06, P<0.001), the number of Dcx positive cells was significantly higher in the NT3-chitosan group than in the injury group (F=62.367, P<0.001), and the number of BrdU/Dcx positive cells was significantly higher in the NT3-chitosan group than in the control group (F=33.527, P<0.001). Conclusion NT3-chitosan could activate NSCs in the SVZ, and promote endogenous neurogenesis and forelimb function recovery in rats after motor cortex injury.
