👉 Trophoblastic is a term used in medicine to describe cells that are produced by the placenta during pregnancy. These cells are responsible for producing hormones and enzymes that help in the development of the fetus, such as progesterone, which plays a crucial role in regulating the menstrual cycle. The trophoblast cells are also known as trophoblastic endometrial stromal cells (TESSs) and they can be found on the surface of the placenta.
