Abstract

Communication during early pregnancy is essential for successful reproduction. In this review we address the beginning of the communication between mother and developing embryo; including morphological and transcriptional changes in the endometrium as well as epigenetic regulation mechanisms directing the placentation. An increasing knowledge of the embryo–maternal communication might not only help to improve the fertility of our farm animals but also our understanding of human health and reproduction.

Additional keywords: bovine, implantation, imprinting, interferon, interleukin, methylation, oestrogen, porcine.
