Because of the physiological and immunological similarities between pigs and humans, porcine embryonic stem cells (ESCs) have been identified as important candidates in preliminary studies on human disease. A comparative understanding of pig ESCs with the human is required to achieve these goals. To gain insights into pig stem cells, the transcriptome of pig ES-like cells were compared with pig preimplantation embryos and human/mouse pluripotent stem cells by RNA-seq analysis. As a result, pig stem cells were more similar to late epiblasts of pig preimplantation embryos than early ICM as revealed by transcriptome analysis, suggesting that pig stem cells are in a developmentally primed state. Moreover, the physiological and biological functions of pig ESCs were more similar to those of human PSCs than to those of mouse PSCs, as determined by direct differentiation and GO/KEGG term analysis. Overall, our data indicate that pig ESCs are in a primed pluripotent state resembling human PSCs. Our findings will facilitate both the development of large animal models for human stem cell therapy and the generation of pluripotent stem cells from other domestic animals for agricultural use.
