Inappropriate materno-fetal resource allocation causes pregnancy complications and abnormal fetal growth with lifelong consequences for both mother and child. The placenta, the site of maternal-fetal exchange, secretes hormones that modify maternal metabolism and thereby impacts the nutrient availability for fetal growth. However, the precise role of placental endocrine function in supporting fetal growth and influencing future health outcomes of the offspring is unknown. To investigate this, I will exclusively delete or over-express Igf2, a driver of placental endocrine cell formation, in placental endocrine cells as a tool to modify placental endocrine function in mice. By examining the effect of altered placental endocrine function on fetal growth, birth outcomes and postnatal offspring metabolism, and identifying the molecular mechanisms involved in programming the postnatal phenotype, we will advance knowledge of the endocrine placenta and its long-term impact on future health.
