The first differentiation event in the formation of the placenta is the formation of trophoblasts, specialized epithelial cells, that ultimately form a physical connection between the embryo and the uterus. Allocation of cells to the trophoblast lineage is dependent on their position at the morula stage.
The placenta normally attaches to the uterine wall, however there is a condition that occurs where the placenta attaches itself too deeply into the wall of the uterus. This condition is known as placenta accreta, placenta increta, or placenta percreta depending on the severity and deepness of the placenta attachment. Approximately 1 in 2,500 pregnancies experience placenta accreta, increta or percreta.
