The layer of cells that surround the embryo is what produces the hormone human chorionic gonadotropin hCG. As the embryo continues to grow, these same cells that produce hCG eventually form into the placenta, which embeds itself into the wall of the uterus. In normal conditions, hCG signals to the body that a pregnancy is underway, and acts to nourish and protect the developing life.
