The maternal–fetal interface in early pregnancy. This is a simplistic drawing for the maternal–fetal interface. During early pregnancy, the anchored placental villi filled with trophoblast cell column interact with the maternal endometrium, forming the maternal–fetal interface. The inner cytotrophoblasts (CTB) fuse to form the outer syncytiotrophoblasts (STB), and the extravillous trophoblasts (EVT) invade the endometrium, uterine glands and the uterine spiral arteries. Maternal immune cells also participate in this process for maintenance of immune balance
