The porcine conceptus undergoes rapid differentiation and expansion of its trophoblastic membranes between days 11 and 12 of gestation. The production of estrogen, the porcine embryonic pregnancy recognition signal, by the conceptus increases with trophoblast elongation. A complex interplay of estrogen signaling and prostaglandin (PG) metabolism in the endometrium finally results in prevention of luteolysis. Conceptus attachment to the uterine surface epithelium starts a...

Summary. Transcriptome studies of the bovine endometrium during early pregnancy and during the estrous cycle have been performed using DNA microarrays and RNA sequencing to identify genes associated with establishment and maintenance of pregnancy. The results of these studies are reviewed and the identified differentially expressed genes (DEG) are compared to define the overlaps between studies and technical platforms. Good overlaps were found for upregulated ...
