Understanding angiogenic function in normal term pregnancies

Angiogenic Function at Normal Term on Placenta

Centre Hospitalier Intercommunal Creteil · NCT03981653

This study looks at how certain cells in healthy pregnancies help with blood vessel growth in the placenta to see if it can lead to better treatments for pregnancy problems like pre-eclampsia.

What this trial studies

This observational study investigates the angiogenic function of trophoblasts in placentas from healthy pregnancies at term. It aims to analyze the expression of pro- and antiangiogenic factors, such as placenta growth factor (PlGF) and soluble FMS-like tyrosine kinase-1 (sFlt-1), in human differentiated trophoblastic cells. The study will also explore the effects of various chemical compounds on placental functions and trophoblastic differentiation, potentially identifying therapeutic targets for pregnancy-related pathologies like pre-eclampsia and intrauterine growth restriction. By measuring gene and protein expression variations, the research seeks to enhance understanding of placental pathophysiology.

Who should consider this trial

Good fit: Ideal candidates include women with strictly normal pregnancies or those with specific complications like gestational diabetes or pregnancy cholestasis, who are scheduled for cesarean delivery after 37 weeks.

Not a fit: Patients with multiple pregnancies, known major fetal malformations, or those experiencing pre-eclampsia or intrauterine growth restriction will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new therapeutic strategies for managing pregnancy complications related to placental dysfunction.

How similar studies have performed: While this study explores a specific aspect of placental function, similar studies have shown promise in understanding angiogenic factors in pregnancy-related conditions.
