Summary
This proposal seeks to identify the critical maternal and embryonic placental factors that regulate the formation of a healthy placenta and thus a healthy pregnancy and baby. Currently there is no way of identifying whether the placenta is forming adequately. The proposed studies are a necessary first step in identifying therapeutic targets for diseases associated with a poorly formed placenta, such as preeclampsia.
HtrA4-induced Endothelial Dysfunction In Early-onset Preeclampsia

Summary
Preeclampsia (PE), a life-threatening disorder of pregnancy, is characterized by a sudden increase in blood pressure in association with wide-spread endothelial dysfunction. Placenta-derived factors are believed to cause PE development. Our recent studies have identified that HtrA4, a placenta-specific serine protease may contribute to endothelial dysfunction. This study will investigate the mechanisms of HtrA4-induced endothelial dysfunction.
Implantation of an embryo into the uterus & development of a functional placenta are critical to initiate & continue a pregnancy. Implantation failure causes infertility and is a major bottle-neck in IVF. Placental insufficiency leads to pregnancy loss, under-developed fetuses & a life-threatening pregnancy-specific disease preeclampsia. This application will investigate how a woman’s uterus works for implantation and placental development, how to increase IVF success and diagnose & potentially ....Implantation of an embryo into the uterus & development of a functional placenta are critical to initiate & continue a pregnancy.

Interstitially Invasive Trophoblast Of The Murine Placenta: Developmental Origins, Functions And Gene Expression.

Summary
Due to the obvious limitations to studying human pregnancy, the mouse has become a valuable model. However, invasion of the placenta into the uterine wall and vasculature, critical for successful pregnancy, is poorly understood in the mouse. The aims of the proposal are designed to gain a better understanding of these processes in mice and will provide a more accurate model system to study serious pregnancy complications resulting from abnormal placental invasion, such as preeclampsia.

Summary
We must understand the role of growth control genes in the growth of the human placenta. The reason is that in several significant placental disorders, placental formation is abnormal and prevents the placenta from functioning efficiently. This in turn, impacts on the growth of the developning fetus. A variety of established and innovative methods described in this project will determine the functions of the placental growth control genes and may lead to novel therapeutic targets.
