ABSTRACT
Objective:To isolate and identify the phenotype and biological characteristics of human placental microvascular endothelial cells(HPMEC).Methods:The HPMEC were isolated from term placenta and cultured in ECM medium. The morphology of the cells was observed under microscope. The functions of HPMEC were detected by uptake of Dil-Ac-LDL, tube formation and cell proliferation. Western Blot was used to detect the expression of endothelial nitric oxide synthase (eNOS), PROKR1 and PROKR2.Results:The HPMEC isolated from the placenta could expressed eNOS, PROKR1 and PROKR2, and were capable of the functions of Dil-Ac-LDL uptaking, tube formation, cell proliferation.Conclusions:HPMEC can be isolated from the placenta, proliferate effectively in vitro and maintain the characteristics of endothelial cells.
