摘要

Background: ?Aging-associated functional impairment of endothelial progenitor cells (EPCs) contributes to delayed re-endothelialization after vascular injury and exaggerated intimal hyperplasia (IH). This study tested if bone marrow (BM) rejuvenation accelerates post-injury re-endothelialization in aging mice. Methods and Results: ?Using BM transplantation (BMTGfp→Wild), youngGfp to youngWild (YTY), oldGfp to oldWild (OTO), youngGfp to oldWild (YTO), and oldGfp to youngWild (OTY) groups were created. After vascular injury, IH was significantly greater in the old group than the young group (P+KDR+ EPCs mobilized in the circulation induced by vascular injury was higher in young, YTO, and YTY mice than in old mice (P+ BM cells from the young, YTO, and YTY groups had better migration and adhesion capacities than those from the old group (P
