Role of nitric oxide in proliferation and secretion effect of vascular endothelial cells induced by vascular endothelial growth factor / 中国病理生理杂志

ABSTRACT

AIM: To investigate the role of nitric oxide in proliferation and secretion of vascular endothelial cells induced by vascular endothelial growth factorr (VEGF). METHODS: The in vitro cultured vascular endothelial cells of rabbit aorta were divided into control group, VEGF-treated group and VEGF+L-NAME treated group, the absorbance (A) value of vascular endothelial cells, endothelin-1(ET-1) and von Willebrand factor (vWF) in the supernatant were examined by WST-1 assay, radioimmunoassay and ELISA. RESULTS: The A value in VEGF and VEGF+L-NAME treated group were higher than that in control group (P
