part of part of capable of epithelial cell oviduct secretory cell luminal endometrial unciliated epithelial cell 2024-10-22T12:02:23Z The luminal endometrial unciliated epithelial cell expresses WNT7A, and LGR5 during the proliferative phase, transitioning to express VTCN1 and SULT1E1 in the early secretory phase, and LEFTY1, IL6, and PTGS1 in the mid- to late-secretory phases. An epithelial cell that is part of the endometrial luminal epithelium, forming a continuous layer lining the uterine cavity. This cell undergoes cyclical changes during the menstrual cycle, proliferating under estrogen in the proliferative phase, and differentiating under progesterone in the secretory phase to prepare for potential implantation. During the window of implantation, this cell changes from a tall columnar shape to a shorter columnar or cuboidal form, loses polarity, and becomes receptive to blastocyst implantation. luminal epithelial cell of endometrium secretion by cell endometrium luminal epithelium
