Cytotrophoblast (Cytotrophoblast)

The cytotrophoblast is the inner part of the trophoblast and maintains its cellular structure. It does not penetrate the uterine tissue and ensures the development and nutrition of the embryo.

Around the middle of the third month of pregnancy, the cytotrophoblast begins to disappear. This is due to the fact that the embryo begins to develop independently and requires less nutrients from the mother.

However, despite the disappearance of the cytotrophoblast, it continues to play an important role in fetal development. It provides nutrients and oxygen to the embryo and also protects it from infections and other threats.

Thus, the cytotrophoblast plays a key role in the development of the embryo and is an important link in the pregnancy process.

The name “cytotrophoblast” comes from the Greek word “cito” - “cell” (“cytus”) and the Greek root “trophos” (“to feed, feed”) (“trophon”), according to which this term denotes a special intratrufoblastic cell , whose function is to produce the main protein substance of the fertilization substance. From such a cell, the endometrium (the inner layer of the uterus) and also the placenta are subsequently formed.

Cytotrophbolastic formation occurs in the membranes (amniotic fluid). The phenomenon of formation of trophoblastic masses inside the fetal egg is called trophoblastic transvaginal invasion. Sometimes this condition is also called lymphoreticular
