Abstract:It is well known that DNA damage can cause apoptosis. However, whether apoptosis and its metabolites contribute to DNA repair is largely unknown. In this study, we found that apoptosis‐deficient Fasmut and Bim−/− mice show significantly elevated DNA damage and premature cellular senescence, along with a significantly reduced number of 16,000 g apoptotic vesicles (apoVs). Intravenous infusion of mesenchymal stromal cell (MSC)‐derived 16,000 g apoVs rescued the DNA damage and premature senescence in Fasmut and B… Show more
