It was developed in 1985 by Leighton et al.20 and refined according to the requirements of an industrial laboratory by Bagley et al.,21 and to the use of eggs on day 10 of embryonation rather than day 14.

Webtrophoblast: [ trof´o-blast ] the peripheral cells of the blastocyst , which attach the zygote (fertilized ovum ) to the uterine wall and become the placenta and the membranes that nourish and protect the developing organism. The inner cellular layer is the cytotrophoblast and the outer layer is the syntrophoblast .
WebFor 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 directly below the syncytiotrophoblast and its development begins from the first week of gestation. WebCHM can occur at any maternal age but is most common in younger women (late teens) and those of advanced maternal age (ages 40 to 50). 1 Hydatidiform molar pregnancy is more common in Asian countries than in the United States.4. PHM pregnancy is much less frequent than CHM and constitutes 15% to 30% of molar pregnancy.

The core of placental villi contain mesenchymal cells and placental blood vessels that are directly connected to the fetus’ circulation via the umbilical cord.
