Objective To investigate the effects of CXC chemokine receptor-2( CXCR2) and CXC chemokine receptor-4(CXCR4) on migration,proliferation and secretion of vascular endothelial growth factor( VEGF) of HeLa cells. Methods HeLa cell migration was detected with Transwell method. Effects of CXCR2 and CXCR4 on the proliferation of the HeLa cells was detected with 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide( MTT)assay. The expression of VEGF of the HeLa cells was detected with enzyme-linked imm...
