Abstract

DNA methylation profile, consisting of tissue-dependent and differentially methylated regions (T-DMRs), has elucidated tissue-specific gene function in mouse tissues. Here, we identified and profiled thousands of T-DMRs in embryonic stem cells (ESCs), embryonic germ cells (EGCs) and induced pluripotent stem cells (iPSCs). T-DMRs of ESCs compared with somatic tissues well illustrated gene function of ESCs, by hypomethylation at genes associated with CpG islands and nuclear events including transcriptional regulation network of ESCs, and by hypermethylation at genes for tissue-specific function. These T-DMRs in EGCs and iPSCs showed DNA methylation similar to ESCs. iPSCs, however, showed hypomethylation at a considerable number of T-DMRs that were hypermethylated in ESCs, suggesting existence of traceable progenitor epigenetic information. Thus, DNA methylation profile of T-DMRs contributes to the mechanism of pluripotency, and can be a feasible solution for identification and evaluation of the pluripotent cells.
