trophoblast
Implantation cell layer
A trophoblast is the outer layer of cells in an early embryo that attaches to the uterine wall and develops into the placenta.
These cells provide nutrients to the embryo and form the interface between mother and fetus.
The term appears in discussions of pregnancy, fertility treatments, and embryonic development.
