The placenta is essential for fetal-maternal exchange and healthy pregnancy however the factors that are required for the placenta to form are poorly understood. We will investigate how the placenta develops in mice and which are the most important factors that are required for a health placenta to form.
Reprogramming Human Fibroblasts Into Induced Trophoblast Stem Cells

Summary
We have been able to generate artificial human trophectoderm which is the tissue that creates the placenta. This will allow us to do research in how the genes control the fate of these cells without the need of human embryos or placenta. We anticipate that the derivation and characterising these cells will revolutionise placenta research, which in turn will contribute to the establishment of new therapies for placenta disease and infertility.
Cell-cell fusion is critical for the development and transport capacity of the placenta during pregnancy. Impairments in this process occur in pregnancy complications such as preeclampsia (PE). We have identified a novel pathway (LY6E) regulating placental cell-cell fusion which is also dysregulated in human pregnancies complicated by PE. In the current proposal we will investigate the mechanisms by which LY6E mediates cell-cell fusion and examine its role in the development of PE.

Summary
Vitamin D deficiency affects about 1 billion people worldwide, including up to 80% of Australians depending on age, skin colour and sun exposure. Vitamin D deficiency has now been associated with a large number of common diseases of aging and with pregnancy complications. This proposal will use human pregnancy serum and placenta, as well as mouse gene knockout models, to determine the hitherto unknown roles of vitamin D in development of the placenta and health of mother and baby.
