Embryo implantation initiates the interaction of the blastocyst with the uterus and occurs within a specialised crypt formed by uterine epithelial cells. Here, using 3D imaging techniques of wild type and mutant uteri, the authors show that crypt formation occurs with preexisting glands of the uterus, opening communication between glands and the implanting embryo.
