Allo‐Antigenicity of Trophoblast Cells*
American Journal of Reproductive Immunology, 1983ABSTRACT: Trophoblast cells of the placenta represent the frontier of the conceptus at the feto‐maternal interface, exposed to the maternal immune system. The presence or the absence of major histocompatibility (MHC) antigens on trophoblast cells, thus, is a key determinant of immune interactions between the mother and the allogeneic fetus during ...

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.

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 ...

Transferrin Expression by Placental Trophoblastic Cells
Placenta, 2004Transferrin (TF), a 76-80 kDa glycoprotein, is responsible for the transport of iron to cells within both the fetal and maternal systems, but it does not cross the multiple cell layer barrier of the placenta. Recent findings that both rat and human placental cells produce TF indicated that placental TF may function in some manner to transport or ...

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.

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.

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.

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,
