The effects of vascular endothelial growth factor (VEGF) on neural differentiation of human embryonic stem cells (hESCs) in vitro and the possible mechanism were observed. The hESCs lines,TJMU1 and TJMU2, were established and stored by our laboratory, hESCs differentiated into neuronal cells through embryonic body formation. In this induction process, hESCs were divided into three groups: group A, routine induction; group B, routine induction+10 ng/mL VEGF; group C, routine in-duction+10 ng/mL VEGF+10 ng/mL VEGFR2/Fc. OCT4, Nestin and GFAP in each group were de-tected by RT-PCR, and the cells expressing Nestin and GFAP were counted by immunofluorescence.The percentage of Nestin positive cells in group B was significantly higher than in groups A and C,while the percentage of GFAP positive cells in group B was significantly lower than in groups A and C (P0.05). It was concluded that VEGF, via VEGFR2, stimulated the neural differentiation of hESCs in vitro.
