Bovine pre-transfer endometrium and embryo transcriptome fingerprints as predictors of pregnancy success after embryo transfer (embryo study)

ABSTRACT: The aberrant gene expression in the uterine endometrium and embryo has been the major causes of pregnancy failure in cattle. Therefore, selecting cows having adequate endometrial receptivity and embryos of better developmental competence based on the gene expression could increase the number of calves produced by each cow during its productive life time. We used endometrial and embryo biopsy technology in conjunction with the pregnancy outcome information to establish a direct link between the pre-transfer endometrial or in vivo derived embryo gene expression and pregnancy outcome after embryo transfer. Endometrial samples were collected from Simmental heifers at day 7 and 14 of the estrous cycle, one cycle prior to embryo transfer. In the next cycle, embryo biopsies consisting of 60-70%
