Early human trophoblast

  • Y. W. Loke


Trophoblast represents that layer of the placenta which is in direct contact with maternal tissues and is, therefore, expected to play an important role in all aspects of fetal-maternal interaction. Although trophoblast comes to line the whole uterine cavity during gestation, it is at the placental implantation site where these cells are most numerous and where they penetrate deepest into decidua and myometrium. The present review will focus on some phenotypic and functional characteristics of these placental trophoblast populations during early pregnancy.
