Study of Pregnancy Pathologies Associated With Placental Abnormalities

Pregnancy pathologies can occur from implantation until childbirth. Clinical and scientific investigators are interested in the study of the mechanisms of development of these pathologies and aim to develop therapies to treat them. The investigators need to collect samples, especially placental samples, following abortions, term, and premature deliveries. Abortions will allow investigators to have non-pathological placental material up to 13 weeks. This material will serve as a reference for understanding the histological changes that occur in normal placentas collected at term of pregnancy. The latter, will in turn, be compared with the placentas collected during premature deliveries. Also, the abortion product will be cultivated in an environment mimicking the pathology of preeclampsia. This study will allow investigators to advance the understanding of the pathophysiological mechanisms of the placenta. The investigators are internationally recognized for its research on these thematic.
