Endomitosis in human trophoblast

Human Genetics, 1982
Endopolyploidy, which arises through the duplication of DNA without accompanying nuclear division, occurs in large numbers of lower and higher plants and animals, including the best known, the salivary gland nuclei of Drosophila. Endomitosis is one of the processes leading to endopolyploidy, in which the stages of mitosis (prophase, metaphase, anaphase)

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.

Macrophage-Trophoblast Interactions

2006
During implantation and pregnancy, the invading trophoblast population is within close contact to maternal immune cells, particularly macrophages. During this period, a low level of trophoblast cell death occurs as part of the normal process of tissue renewal.

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 ...
