The objective of this study is to better understand the regulation of trophoblast expression of pro- and antiangiogenic factors such as placenta growth factor (PlGF) or Soluble FMS like tyrosin-kinase-1 (sFlt-1), and more particularly on human differentiated trophoblastic cells from "healthy" placentas. The measurement of the variation in gene and protein expression of placental angiogenic factors will provide a better understanding of their pathophysiology.
Secondary objectives are the study of trophoblastic differentiation and placental functions, and the study of the impact of chemical compounds on the biological functions of the placenta. To do this, these "healthy" placentas may be exposed to different factors that promote the occurrence of specific pregnancy pathologies such as pre-eclampsia and vascular intrauterine growth restriction (IUGR), caused by placental dysfunction. This will make it possible to test molecules and vector approaches targeted directly at the trophoblast, in order to consider therapeutic targets, which do not exist to date.
