Successful embryo implantation is a critical step in establishing pregnancy and requires
appropriate preparation of the endometrium to provide a transient state of “uterine
receptivity.” The most essential of the molecular events determining receptivity may therefore
provide potential targets for postcoital contraception. Using the mouse as a model, we
identified molecules specifically regulated in the endometrium at very early implantation:
these were monoclonal nonspecific suppressor factor beta (MNSFβ), splicing factor SC35, a …
