Vascular Endothelial Growth Factor and Its Receptors in the Placental Villi of Pregnant Patients with Pre-Eclampsia
Tóm tắt
Comparative morphological study of the placentas from women with pre-eclampsia of different severity was carried out. The expression of vascular endothelial growth factor and its receptors (VEGFR-1, VEGFR-2, VEGFR-3) was studied by immunohistochemical methods. Branched angiogenesis processes predominated in the placentas of patients with pre-eclampsia. The syncytiocapillary membranes were thickened, the number of syncytial buds was greater than normally. Immunohistochemical studies showed high expression of VEGF and VEGFR-1 and low expression of VEGFR-2 in the placental villous structures.
