Characterization of the Endometrial Transcriptome in Early Diestrus Influencing Pregnancy Establishment in Dairy Cattle after Transfer of In-Vitro Produced Embryos

In this study, we sequenced the RNA content of endometrial biopsies from Holstein cows at day 6-8 to identify candidate genes and describe biological mechanisms for endometrium receptivity and pregnancy establishment upon transfer of IVP embryos. 23 RNA-Seq profiles of endometrial biopsies collected from 23 Holstein cows on day 6-8 in dioestrus. In the same animals one in vitro produced embryo was transferred on day 6-8 in the following cycle. The pregnancy status was determined after slaughter on day 26-47.
