Cytotrophoblast and trophoblast
WebNov 1, 2024 · Two recently developed models, trophoblast organoids and trophoblast stem cells (TSCs), are useful tools to further the understanding of human placental development. Both differentiate from villous cytotrophoblast (VCT) to either extravillous trophoblast (EVT) or syncytiotrophoblast (SCT). Here, we compare the transcriptomes … Webtrophoblast [trof´o-blast] the peripheral cells of the blastocyst, which attach the zygote (fertilized ovum) to the uterine wall and become the placenta and the membranes that nourish and protect the developing organism. The inner cellular layer is the cytotrophoblast and the outer layer is the syntrophoblast. Miller-Keane Encyclopedia and Dictionary ...

WebAs nouns the difference between cytotrophoblast and trophoblast is that cytotrophoblast is (cytology) the inner layer of the trophoblast while trophoblast is (cytology) the membrane of cells that forms the wall of a blastocyst during early pregnancy, providing nutrients to the embryo and later developing into part of the placenta.

Trophoblasts are specialized cells of the placenta that play an important role in embryo implantation and interaction with the decidualized maternal uterus. The core of placental villi contain mesenchymal cells and placental blood vessels that are directly connected to the fetus’ circulation via the umbilical cord. This core is surrounded by two layers of trophoblasts, the cytotrophoblast and the syncytiotrophoblast. The cytotrophoblast is a layer of mono-nucleated cells that resides …
WebSeveral trophoblast phenotypes, including cytotrophoblast, syncytiotrophoblast, and extravillous trophoblast, emerge during gestation. To clarify the lineage relationship between these subtypes, we profiled p63 localization in developing and term placental tissue, as well as in trophoblastic tumors, using antibodies specific to full-length (TAp63) … casanova dvdWebWe found that LIMK1 immunoreactivity mirrored HIF-2α in the human placenta in utero and that LIMK1 activity regulated human cytotrophoblast cytoskeletal integrity, matrix metallopeptidase-9 secretion, invasion, and differentiation in vitro. Importantly, we also found that LIMK1 levels are frequently diminished in the preeclampsia setting in vivo. casanova du bois hengstWeb1 day ago · Introduction.
