Cell adhesion in endometrial epithelium is regulated to maintain the continuity and protectiveness of the luminal covering cell layer while permitting interstitial implantation of the embryo during a restricted period of about 4 days. Many apparently normal embryos fail to implant, and epithelial-embryo adhesion remains a poorly understood phenomenon. After menstruation, epithelial regeneration occurs by epiboly from the basal residues of glands, an activity that requires migration on extracellular matrix as well as cell-cell cohesion. Here we review current knowledge of adhesion molecules in the epithelium.
子宫内膜上皮细胞的黏附受到调节,以维持腔面覆盖细胞层的连续性和保护作用,同时允许胚胎在大约 4 天的限制时间内在间质中植入。许多看似正常的胚胎无法植入,上皮-胚胎黏附仍然是一个了解甚少的现象。月经后,上皮通过从腺体的基底残留物内卷发生再生,这一活动需要在细胞外基质上迁移以及细胞-细胞黏附。在这里,我们综述了上皮细胞中黏附分子的最新知识。
