Preeclampsia: the in vivo milieu leads to cytotrophoblast dysregulation

ABSTRACT: During human pregnancy, placental cytotrophoblasts invade the uterus and its blood vessels, anchoring the progeny and rerouting maternal blood to the embryo/fetus. In preeclampsia, cytotrophoblast invasion is restricted and blood flow to the placenta is reduced. The causes of restricted cytotrophoblast invasion are unknown. Here, preeclampsia and control cytotrophoblasts were cultured for 48 h to allow differentiation/invasion. In various severe forms of preeclampsia ± intrauterine growth restriction, global transcriptional profiling revealed common aberrations in cytotrophoblast gene expression that resolved with culture. Villous cytotrophoblasts were isolated from preeclampsia placentas (PRE, n=5) and placentas of preterm labor patients without signs of infection (PTL, n=5), which serve
