DNA methylation (DNAm) is a key biomarker of aging, with age-related DNAm changes being well-characterized. Here, the authors show that low-methylated regions (LMRs) bound by PRC2 in embryonic stem cells gain methylation with age in somatic cells, proposing the “PRC2-AgeIndex” as a universal biomarker of cellular aging.
