WebFeb 10, 2024 · For its part, the cytotrophoblast forms the innermost layer of the trophoblast. Basically, it is an irregular layer of ovoid cells with a single nucleus and that is why they are called mononuclear cells. The cytotrophoblast is located directly below the syncytiotrophoblast and its development begins from the first week of gestation. The trophoblast (from Greek trephein: to feed; and blastos: germinator) is the outer layer of cells of the blastocyst. Trophoblasts are present four days after fertilization in humans.
