The Multiple Roles of EG-VEGFPROK1 in Normal and Pathological Placental Angiogenesis

الملخص EN

Placentation is associated with several steps of vascular adaptations throughout pregnancy.

These vascular changes occur both on the maternal and fetal sides, consisting of maternal uterine spiral arteries remodeling and placental vasculogenesis and angiogenesis, respectively.

Placental angiogenesis is a pivotal process for efficient fetomaternal exchanges and placental development.

This process is finely controlled throughout pregnancy, and it involves ubiquitous and pregnancy-specific angiogenic factors.

In the last decade, endocrine gland derived vascular endothelial growth factor (EG-VEGF), also called prokineticin 1 (PROK1), has emerged as specific placental angiogenic factor that controls many aspects of normal and pathological placental angiogenesis such as recurrent pregnancy loss (RPL), gestational trophoblastic diseases (GTD), fetal growth restriction (FGR), and preeclampsia (PE).

This review recapitulates EG-VEGF mediated-angiogenesis within the placenta and at the fetomaternal interface and proposes that its deregulation might contribute to the pathogenesis of several placental diseases including FGR and PE.

More importantly this paper argues for EG-VEGF clinical relevance as a potential biomarker of the onset of pregnancy pathologies and discusses its potential usefulness for future therapeutic directions.
