Abstract:
AIM: To observe the effects of vascular endothelial growth factor(VEGF) on the proliferation and differentiation of neural stem cells(NSCs) of rats in vitro.METHODS: NSCs isolated from the hippocampal gyrus of SD rats were primary cultured and subcultured,and then divided into two groups:(1) the cells in VEGF group were treated with 150 ?g/L VEGF in the culture system,and VEGF was removed at the 7 th day;(2) control group(without VEGF treatment).The cellular morphology of two groups was observed by contrast phase microscope.Nestin and NF-200 expressing cells were detected via immunofluorescence method.The percentages of the immunostaining positive cells in each group at the 7 th day and at the 11 th day were determined.RESULTS: At the 7 th day,the percentage of nestin positive cells in VEGF group was 52.19%?7.95%,vs 29.26%?4.12% in control group(P
