The trophectoderm is one of the earliest cell types to differentiate in the forming mammalian embryo. It is responsible for the initial implantation and the formation of the trophoblast components of the placenta, an organ essential for nutrient and waste exchange between the fetus and its mother.

Microarray Analysis of Trophoblast Cells
2005A complex repertoire of trophoblast gene products governs the multifaceted functions performed by the placenta during the relatively short period of pregnancy. Cloning and sequencing the human as well as other mammalian genomes allow investigators to gain better insight into the function of trophoblast genes.

The placenta is essential for implantation of the mammalian embryo into the uterus, protection of the developing fetus from the maternal immune system, establishment of a nutrient/waste exchange system between the maternal and fetal compartments, and production of pregnancy-specific hormones that regulate maternal and fetal physiology.

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

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.

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

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.

Isolation and Characterization of Rat Trophoblast Cells
American Journal of Reproductive Immunology and Microbiology, 1988ABSTRACT: Previous immunohistochemical studies of the rat placenta using specific alloantisera and/or monoclonal antibodies showed that the basal zone trophoblasts stained for Pa and Aa class I major histocompatibility complex (MHC) antigens and for the human SP1‐related antigen.

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

Hypoxia and Lactate Production in Trophoblast Cells
Placenta, 2007The etiology of preeclampsia is unknown but is thought to be related to hypoxia in the placenta. We previously reported that the enzyme lactate dehydrogenase (LDH) has increased activity and gene expression in placentas from preeclamptic pregnancies [Tsoi SCM, Zheng J, Xu F, Kay HH.
