Cytotrophoblast and trophoblast
WebCytotrophoblasts, the inner layer of villous trophoblasts, are composed of proliferative stemlike cells, characterized by expression of p63. The isoform of p63 predominantly expressed in these cells is the N-terminal truncated (dNp63) form, the same isoform expressed in stem cells of other stratified epithelia (including ectocervical and … WebApr 15, 2024 · The CTB originates two main villus structures: the floating villus, where CTBs fuse to form the multinuclear syncyiotrophoblast (STB) and the anchoring villus ( 17 – 20) ( Figure 1 ). The STB acts as an exchange barrier with the maternal blood to assure nutrients as well as waste and gases exchange with the fetal blood ( 21 ).

Both differentiate from villous cytotrophoblast (VCT) to either extravillous trophoblast (EVT) or syncytiotrophoblast (SCT). Here, we compare the transcriptomes …
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) … Webcytotrophoblast and syncytiotrophoblast two layers of trophoblast lined by extraembryonic somatic mesoderm trophoblast and exocoelomic membrane extraembryonic splanchnic mesoderm & both layers of trophoblast none of the above The most distinctive characteristic of a primary chorionic villus is its: outer syncytiotrophoblastic layer
WebPlacentas (n = 6) were collected prospectively from normal pregnant women at term, delivered by cesarean section, at Hutzel Women’s Hospital of the Detroit Medical Center (Detroit, MI, USA), and were then processed at the Perinatology Research Branch, NICHD/NIH/DHHS, for in vitro trophoblast experiments. For cytotrophoblast isolation, …
WebWe 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.
