The mechanism of injury on the human glomerular endothelial cells(ciGENC) induced by preeclampsia serum was investigated.Concentration of maternal serum sFlt-1 protein was detected by ELISA.Fluorescently-labeled bovine serum albumin infiltrating through lower chamber of Transwell was measured by multifunction microplate reader.Morphologic change of ciGENC was observed under inverted phase contrast microscope.The concentration of sflt-1 in preeclampsia groups was significantly increased as compared with control group(P<0.01).Permeability in preeclampsia groups was significantly increased as compared with control group(P<0.01).By contrast with severe preeclampsia group,the permeability of ciGENC monolayer in mild preeclampsia group was decreased significantly(P<0.05).Intervention of exogenous VEGF significantly decreased permeability of ciGENC in preeclampsia groups.It was concluded that sFlt-1 increased ciGENC permeability by damaging integrity of endothelial barrier function.
