Research Interests

• Dr. Fant's research focuses on placental development as a model to understand the mechanisms underlying fetal growth and development using both human and mouse models. His laboratory was the first to demonstrate that insulin-like growth factors (IGFs) are produced by the placenta and act locally to regulate placental development. It also demonstrated that placental mesenchymal cells are important components of the placenta's intrinsic developmental program, exhibiting developmentally regulated proliferation rates and growth factor responsiveness. Currently the laboratory is examining the role of Plac1 (Placenta-specific1), a novel X-linked gene, in supporting normal fetal development. Using a mutant mouse model, an essential role for Plac1 in normal placental and embryonic development was demonstrated. Knockout mice exhibit placentomegaly, intrauterine growth retardation (IUGR), and reduced viability. More recently, Plac1 expression was also demonstrated in the fetal brain and linked to the development of postnatal hydrocephalus, identifying Plac1 as a novel gene important in brain development.
