Biology of human trophoblast

International Journal of Gynecology & Obstetrics, 1998
AbstractIn order to elucidate the regulation of placental growth, we have characterized the expression of proliferating cell nuclear antigen (PCNA), apoptotic DNA fragmentation and bc1‐2 protein in human placenta during pregnancy. PCNA and bc1‐2 protein expression were examined by immunohistochemical techniques, while the occurrence of apoptotic DNA ...

The Ultrastructure of Molar Trophoblast

Australian and New Zealand Journal of Obstetrics and Gynaecology, 1973
Trophcblastic tumours have a high incidence in South East Asia (Acosta‐Sison, 1959; Chun et al., 1964). Most of the reports on the ultrastructural appearances of hydatidi‐form mole have come from Japan (Mori et al., 1960; Kosaka, 1964) and the United States of America (Wynn and Davies, 1964; Gonzales‐Angulo et al., 1966).

Placental Site Trophoblastic Tumors and Epithelioid Trophoblastic Tumors

Hematology/Oncology Clinics of North America
Placental site trophoblastic disease (PSTT) and epithelioid trophoblastic tumor (ETT) are the rarest forms of gestational trophoblastic neoplasia (GTN) with unique clinical features and treatment considerations. Unlike other GTN, human chorionic gonadotropin (hCG) is minimally, if at all, elevated.

Extravillous Trophoblast, Trophoblastic Invasion, and Fibrinoid

2010
The nonvillous parts of the placenta include the chorionic plate, cell islands, cell columns, placental septa, basal plate, marginal zone, and fibrinoid deposits (Fig. 8.1). These structures do not participate in maternofetal exchange, but have mechanical and metabolic functions.

Placenta Trophoblast Fusion

2008
It has been known for more than 150 years that syncytial fusion is a normal feature in biological systems. In humans there are two larger syncytial tissues: skeletal muscles fibers and placental syncytiotrophoblast. Other fusion events take place as well from fertilization of the oocyte to infection of human cells by enveloped viruses (however, the ...

Persistence of abnormal trophoblast

American Journal of Obstetrics and Gynecology, 1965
Abstract 1. This is a case report of a patient who had a twin pregnancy associated with a hydatidiform mole. 2. This was followed by a chorioadenoma destruens and apparent large lung metastasis which eventually cleared. 3. The patient developed apparent related ovarian pathology subsequent to the discovery of trophoblastic cells in pelvic ...

[Trophoblastic gestational disease: a placental site trophoblastic tumor and an epithelioid trophoblastic tumor].

Annales de pathologie, 2004
Placental site trophoblastic tumor and epithelioid trophoblastic tumor are rare gestational trophoblastic tumors. They both appear in the same context and follow the same course. We report two cases in patients aged 44 and 20 years. These lesions usually affect young women with a history of multiple gestations.
