Apolipoprotein E (APOE) is a lipoprotein particle component and is genetically linked to human longevity and Alzheimer’s disease; however, the mechanisms that link APOE and aging are incompletely understood. Here, Zhao et al. show that APOE drives cellular senescence in aged human mesenchymal progenitor cells by destabilizing heterochromatin.
