Human Trophoblast Progenitor Cells Express and Release Angiogenic Factors
Trophoblast stem cells develop from polar trophoectoderm and give rise to the cells that generate the placenta. Trophoblast cells are responsible for the uterinal invasion and vascular remodeling during the implantation of the embryo. However this knowledge is not yet to be confirmed for trophoblast progenitor cells (TPCs). In this study, we aimed to demonstrate that human TPCs (hTPCs) express ...
متن کاملAdhesion molecules in human trophoblast - a review. I. Villous trophoblast.
In the placental villus, cells attach to basement membrane via integrin alpha6beta4 and adhere both laterally and apically to their neighbours. The most prominent adhesive specialisation seen using the electron microscope is the desmosome, which connects cytotrophoblast cells (CTB) laterally and also contributes to the attachment of CTB to the overlying syncytium. However, numerous cadherins an...
متن کاملAdhesion molecules in human trophoblast - a review. II. extravillous trophoblast.
At the tips of anchoring villi, cytotrophoblast (CTB) proliferation leads to a process of multilayering in which cells lose their attachment to the villous basement membrane and develop into columns, within which they adhere to one another using desmosomes, with associated intermediate filament bundles. Non-desmosomal cadherins, tight junction proteins and other adhesion molecules are also pres...
متن کاملTrophoblast contact deactivates human neutrophils.
Trophoblasts are fetal epithelial cells that form an interface between mother and offspring. To evaluate their anti-inflammatory capacity, we tested the hypothesis that trophoblasts deactivate neutrophils using single-cell assays. Several biophysical (Ca2+ and NAD(P)H oscillation frequency) and physiological (oxidant production) markers of activated neutrophils revert to a nonactivated phenotyp...
متن کاملControl of human trophoblast function
The trophoblast, i.e. the peripheral part of the human conceptus, exerts a crucial role in implantation and placentation. Both processes properly occur as a consequence of an intimate dialogue between fetal and maternal tissues, fulfilled by membrane ligands and receptors, as well as by hormone and local factor release. During blastocyst implantation, generation of distinct trophoblast cell typ...
