Abstract Epigenetic modifications established in the early developmental stages can have long‐term consequences throughout life. This concept encompasses the possibility of controlling livestock health and diseases by epigenetic regulation during early development. To explore the candidates of epigenetic modifications in early embryos that might exert long‐lasting effects in adulthood, we aimed to obtain genome‐wide histone H3 lysine 27 trimethylation (H3K27me3) profiles of bovine blastocysts and compare these data with those from adult somatic tissues in order to extract common and typical features between them. Bovine blastocysts were produced in vitro and subjected to chromatin immunoprecipitation‐sequencing analysis of H3K27me3. Comparative analysis of the blastocyst‐derived H3K27me3 profile performed using publicly available data from adult muscle, fat, and liver tissues revealed that (1) blastocyst‐specific modifications against somatic tissues were enriched in immune function‐related genes, (2) somatic modifications “sieved” by blastocyst modifications were enriched in biological processes in tissue‐specific trends, (3) the modifications common in blastocyst and each somatic tissue were largely overlapped and enriched in developmentally important genes, including homeobox and imprinted genes. The results of this study produced a genome‐wide H3K27me3 profile of bovine blastocysts and revealed its common and typical features in relation to the profiles of adult somatic tissues.
