European Journal of Cell Biology, 2012 Throughout pregnancy the cytotrophoblast, the stem cell of the placenta, gives rise to the differentiated forms of trophoblasts. The two main cell lineages are the syncytiotrophoblast and the invading extravillous trophoblast.

Placenta, 1999
The mechanisms responsible for prevention of corpus luteum regression during early pregnancy are diverse and appear to have arisen in concert with the evolutionary divergence of placental structure. That used by the sub-order Ruminantia is unique and involves the production of a Type I interferon (IFN), IFN-tau (tau).

Clinics in Obstetrics and Gynaecology, 1982
Molar pregnancy should always be considered as a possible diagnosis in any pregnancy that does not conform to the normal. The practice of subjecting all pregnant women to ultrasound B-scan at their first visit in some centres is commendable, but unfortunately not possible in the areas of high incidence, owing to lack of facilities.

The villous trophoblast of the human placenta is the epithelial cover of the fetal chorionic villi floating in maternal blood. This epithelial cover is organized in two distinct layers, the multinucleated syncytiotrophoblast directly facing maternal blood and a second layer of mononucleated cytotrophoblasts.

Human Fertility, 2004
Trophoblast invasion can be seen as a tightly regulated battle between the competing interests of the survival of the fetus and those of the mother. Successful pregnancy is dependent on the trophoblast invading the mother, attaching the pregnancy to the uterus and securing an adequate supply of oxygen and nutrient to the fetus.

Antibody reactivity against trophoblast and trophoblast products
Journal of Reproductive Immunology, 1985Sensitive immunoassays have been applied to WHO reference bank sera from fertile and infertile women in order to assess any naturally occurring antibody reactive with isolated human placental trophoblast membranes or two separate trophoblast protein products (hCG and SP1).

Placental site trophoblastic tumour and epithelioid trophoblastic tumour
Best Practice & Research Clinical Obstetrics & Gynaecology, 2021Placental site trophoblastic tumour (PSTT) and epithelioid trophoblastic tumour (ETT) are the rarest subtypes of gestational trophoblastic disease (GTD). Their diagnosis is complicated and lacks specific and sensitive tumour markers. They are slow-growing tumours and can occur months to years after any type of antecedent pregnancy.
