Human Trophoblast Invasion

Annals of the New York Academy of Sciences, 1994
Development of the human placenta involves rapid invasion of the uterine wall by fetal trophoblasts, a process with certain similarities to tumor cell invasion. Unlike tumor invasion, however, this unique interaction between genetically dissimilar trophoblast and uterine cells is closely regulated and limited both temporally and spatially by mechanisms

Caviomorph Placentation as a Model for Trophoblast Invasion

Placenta, 2007
The guinea pig and its relatives are promising candidates as animal models for studying trophoblast invasion. The origin, migration routes and kinetics of invasive trophoblast cells were examined in two caviomorph species. Histology and immunohistochemistry were done on placentas from 38 guinea pigs of days 20-47 and 13 degus of days 25-51 of gestation.

Regulation of human trophoblast migration and invasiveness

Canadian Journal of Physiology and Pharmacology, 2002
The human placenta is an invasive structure in which highly proliferative, migratory, and invasive extravillous trophoblast (EVT) cells migrate and invade the uterus and its vasculature. Using in vitro propagated normal first-trimester EVT cells and immortalized EVT cells, which share all of the phenotypic and functional characteristics of the normal ...

In Vitro Analysis of Trophoblast Invasion

2006
Two methods are described for the study of human trophoblast invasion. When first-trimester placental villi are explanted on gels of a permissive extracellular matrix (ECM), a population of pure extravillous trophoblast cells grows out during the following several days from villous tips into the adjacent ECM.

Cellular Nature of the Invasive Mouse Trophoblast

Nature, 1964
IN those types of placentae in which the trophoblast is non-invasive (epitheliochorial) or only very weakly invasive (syndesmochorial) the trophoblast is cellular. However, in the endotheliochorial and haemochorial types of placentae the trophoblast is progressively more invasive and in those species in which it has so far been studied the trophoblast,

Role of decidua in trophoblastic invasion.

Neuro endocrinology letters, 2010
Proliferation, migration and invasion of trophoblastic cells into the maternal endometrium are essential steps in human embryo implantation and placentation. Trophoblast invasion is normally limited in time, only during first and early second trimester of pregnancy, and in space, limited to the endometrium and the proximal third of myometrium.

Trophoblast stem cells, trophoblast invasion, and organoids – advancements in gynecology

Česká gynekologie
The human placenta serves as a vital barrier between the mother and the developing fetus during pregnancy. A defect in the early development of the placenta is associated with severe pregnancy disorders. Despite its complex development, various molecular processes control placental development, and the specialization of trophoblast cells is still not ...

CT Evaluation of Invasive Trophoblastic Disease

Journal of Computer Assisted Tomography, 1985
We report the use of dynamic CT for the evaluation of trophoblastic disease of the uterus. In five cases showing evidence of persistent trophoblastic disease after evacuation of a molar gestation, contrast enhancement of the myometrium demonstrated several hypodense foci surrounded by highly enhanced areas.

Pelvic arteriography in invasive trophoblastic neoplasia

The British Journal of Radiology, 1968
Abstract 1. Arteriographic abnormalities were present in 39 of 43 patients with invasive trophoblastic neoplasia and frequently these abnormalities were gross. 2. The appearances were sometimes characteristic of ITN. The spectrum of abnormality observed overlaps the appearances found in early pregnancy, missed abortion, hydatidiform mole and abdominal ...

C1q Is Involved in Human Trophoblast Invasion

American Journal of Reproductive Immunology, 2007
During the development of human placenta, extravillous trophoblast (EVT) departs from anchoring chorionic villi and invades the maternal decidua. Immunohistochemical analysis of decidua obtained from voluntary abortions showed that C1q was widely distributed in the decidual stroma with intense staining around invading trophoblast, while undetectable in
