Research

 

The Armant lab investigates the biology of trophoblast cells in animal models, human cell lines, and human placental tissue. Our research has contributed to understanding of mechanisms controlling trophoblast invasion, particularly work on integrin signaling in mouse trophoblast cells during blastocyst implantation. More recently, effort has been directed toward mechanisms of human trophoblast survival under oxidative stress, and in the low oxygen environment of the female reproductive tract during the first trimester. We work with physician-scientists on an approach that captures and isolates human trophoblast cells during the first trimester from ongoing pregnancies, using a noninvasive endocervical collection procedure identical to a Pap smear. Trophoblast retrieval and isolation from the cervix (TRIC) is being explored for applications in fetal genetic testing, perinatal disease diagnosis, and translational research to investigate human placentation. The vision of our research is to enhance the management of pregnancy by providing information about placental development acquired in real time with trophoblast cells obtained by TRIC.
