Abstract:
Objective To observe the chemotactic role on umbilical vein endothelial cells of SMMC7721 hepatic(carcinoma) cells with angiopoietin gene expression in order to study the effects of angiopoietin on hepatocellular carcinoma angiogenesis.Methods Angiopoietin gene 1(Ang-1) fragment and Ang-2 fragment was transfected into SMMC7721 liver carcinoma cell line by Lipofectamine induced gene transfection technique.The chemotactic role of SMMC7721 liver carcinoma cell line on umbilical vein endothelial cells was observed through microchemotaxis analysis.Results The chemotactic response of the Umbilical vein endothelial cells was obviously improved with Ang-1 expression (P0.05).Conclusion Ang-1 is a chemotactic factor for vascular endothelial cell and a promoter for angiogenesis,whereas Ang2 does not show obvious chemotactic role.
