Vascular endothelial growth factor, its receptors, and the tie receptors in the placental bed of women with preeclampsia, diabetes, and intrauterine growth retardation.
Placental bed vascular function is compromised in pregnancies complicated by preeclampsia (PE), intrauterine growth retardation (IUGR), and maternal diabetes mellitus (DM). We performed an immunohistochemical analysis of vascular endothelial growth factor (VEGF), its receptors (VEGFR) -1 and -2, and the Tie-1 and -2 receptors in cryostat tissue sections of the placental bed from healthy women (n = 5) and women with PE (n = 5), IUGR (n = 5), and DM (n = 5). VEGF immunoreactivity was stable between the study groups. VEGFR-1 immunoreactivity in the myometrial vascular smooth muscle cells was strongest in the controls. In the myometrial cells, the strongest VEGFR-2 immunoreactivity was seen in women with IUGR. In the decidual vascular endothelial cells, the strongest Tie-1 immunoreactivity was observed in healthy women and in those with DM. Alterations in the placental bed expression of VEGFR-1, VEGFR -2, and Tie-1, but not of VEGF and Tie-2, may be associated with PE, IUGR, or DM.
