Rcho-1 Trophoblast Stem Cells: A Model System for Studying Trophoblast Cell Differentiation
2005The biology of trophoblast cell development can be investigated using in vitro model systems. The Rcho-1 trophoblast stem cell line was derived from a rat choriocarcinoma and is an effective tool for elucidating regulatory mechanisms controlling trophoblast cell differentiation.

Bovine trophoblastic cells are the first cells to differentiate during embryogenesis and play pivotal role in morphological and physiological development of the placenta. We have developed culture systems for bovine trophoblast stem cells isolated from in vitro fertilized blastocysts in the absence of feeder cells.

Sheep trophoblast in monolayer cell culture
Placenta, 1980Methods are described for the preparation and maintenance of ovine trophoblast in monolayer cell culture, and for the preparation of cultured cells for ultrastructural examination. Monolayers grown from dispersed and explanted primary cultures were maintained in consecutive subcultures for periods of 12 to 16 weeks. Towards the end of the first week of

Trophoblast stem cells (TSC) are the precursors of the differentiated cells of the placenta. In the mouse, TSC can be derived from outgrowths of either blastocyst polar trophectoderm (TE) or extraembryonic ectoderm (ExE), which originates from polar TE after implantation. The mouse TSC niche appears to be located within the ExE adjacent to the epiblast,

Intermediate Trophoblast in Germ Cell Neoplasms
The American Journal of Surgical Pathology, 1987One-hundred-twenty-four germ cell tumors and 11 gestational choriocarcinomas were assessed immunohistochemically for the presence of the following placental markers: human chorionic gonadotrophin, human placental lactogen, and pregnancy-specific beta-1 glycoprotein, and for the expression of cytokeratin.

Giant and binucleate trophoblast cells of mammals
Journal of Experimental Zoology, 1993AbstractThe cellular origin, structure, and function of trophoblastic giant cells (GC) and binucleate cells (BNC) are reviewed. Mammals in which these cells have received the greatest attention include rodents, rabbits, and humans (GCs), and ruminants and equids (BNCs). In almost all cases these cells arise from the cytotrophoblast. All are large cells

Ethanol cytotoxic effect on trophoblast cells
Toxicology Letters, 2014Prenatal ethanol exposure may cause both, altered fetal neurodevelopment and impaired placental function. These disturbances can lead to growth retardation, which is one of the most prevalent features in Fetal Alcohol Syndrome (FAS). It is not known whether there is a specific pattern of cytotoxicity caused by ethanol that can be extrapolated to other ...

Connexins and Trophoblast Cell Lineage Development
2005The mouse is a valuable model for studying basic mechanisms of gene regulation in trophoblast cell lineage differentiation. Elements of placental development are conserved across species, including trophoblast proliferation, differentiation, migration, and vessel invasion.

Production of Human Trophoblast Cell Lines
2005Our understanding of important biological phenomena such as invasion, migration, and apoptosis has advanced greatly through the prudent use of in vitro models based on isolated cells in culture. Established cell lines are readily manipulated using simple molecular biological techniques and their abundance as homogenous populations allows the rapid ...
