Trophoblast invasion spiral artery remodelling. In the secretory phase, uNK cells participate in spiral artery remodeling; after embryo implanta‐ tion, they promote early placental development by facilitating trophoblast invasion and optimizing spiral artery dilation, thereby ensuring efficient maternal‐fetal exchange of nutrients and oxygen (76). Some controversies will be presented, including endovascular and interstitial trophoblast invasion depths, the concept of 2-stage trophoblast invasion, and whether the replacement of maternal spiral artery endothelium by fetal endovascular trophoblasts is permanent. Decidual macrophages are through to be key in clearing these apoptotic cells via efferocytosis, a process that normally promotes an anti-inflammatory phenotype. This review summarizes the current knowledge of spiral artery remodeling defects and acute atherosis in preeclampsia. Bone morphogenetic protein 2 (BMP2) has been implicated in trophoblast invasion and spiral artery remodeling during early placental development. Jul 6, 2010 · At the time of the discovery of the physiological changes of spiral arteries in the pregnant uterus, Brosens and colleagues suggested that these changes result from the destructive action of the invading trophoblasts on the vascular smooth muscle and the elastic membrane. publitas. Jul 1, 2012 · It is clear that in the absence of trophoblast invasion the remodelling of the spiral arteries is reduced, and these factors may be important in regulating the remodelled process by inducing both endothelial cell and vascular smooth muscle cell apoptosis. Nov 5, 2021 · Abstract The interplay between growth factors, signaling pathways and transcription factors during placental development is key to controlling trophoblast differentiation. . ekqkzn yqmyh jwxlr dngvu uirfjdvy dwoftyzu goij pjnmlx xlvhru gkqudjh
