Platelet-Derived Growth Factor-AB Limits the Extent of Myocardial Infarction in a Rat Model

Abstract

Aging hearts have impaired angiogenic function as a result of depressed PDGF-B production. Restoration of the dysregulated endothelial PDGF-mediated angiogenic pathway in the aging heart reverses the senescent impairment in cardioprotective angiogenic function and offers a foundation for developing novel therapies for cardiovascular disease in older individuals.
