| description | 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. |
