This research details the creation of CREST, a sophisticated three-dimensional in vitro platform designed to model the complex process of human embryo implantation. By combining primary endometrial stromal and epithelial cells within a specialized hydrogel scaffold, the authors successfully replicated the hormonal transitions of the menstrual cycle, including the critical window of uterine receptivity. The study demonstrates that this model supports the attachment and invasion of human embryos and stem-cell-derived blastoids, achieving higher rates of organized development than previous…
