Placental Endocrinology

  • David L. Healy

Abstract

The placenta is a temporary fetomaternal organ that sustains the growth and nutrition of the developing conceptus. Human beings have a villous hemo chorial placenta in which trophoblast is in direct contact with maternal blood (Fig. 3-1). Syncytiotrophoblast is the outer layer of trophoblast, which is in direct contact with this blood; it derives from the cytotrophoblast, which is most prominent in early pregnancy (Fig. 3-2).
