Abstract:Aging severely limits myocardial regeneration. Delineating the impact of age-associated factors such as short telomeres is critical to enhance the regenerative potential of cardiac progenitor cells (CPCs). We hypothesize that short telomeres induce autophagy and elicit the age-associated change in cardiac progenitor cell fate. We compared mouse strains with different telomere lengths (TL) for phenotypic characteristics of aging and also isolated CPCs from them. Naturally occurring wild mouse strain

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
