Implication

Cardiosphere-derived cells demonstrate superior paracrine potency and myocardial repair efficacy compared to other adult stem cell types in experimental myocardial infarction.

Key Points

To conduct a direct head-to-head comparison of distinct adult stem cell types and subpopulations in vitro for biologic potency and in vivo for functional cardiac repair after myocardial infarction.
Compared human cardiosphere-derived cells (CDCs), bone marrow-derived mesenchymal stem cells (BM-MSCs), adipose tissue-derived mesenchymal stem cells (AD-MSCs), and bone marrow mononuclear cells (BM-MNCs) across differentiation and secretome assays in vitro.
Injected the human cell preparations, as well as purified c-kit+ CDC subpopulations, into mouse models of acute myocardial infarction, evaluating functional recovery, engraftment, and morphology at 3 weeks, with parallel validation using rat-derived cells.
In vitro, CDCs demonstrated the highest myogenic differentiation potency, the greatest angiogenic potential, and elevated secretion of pro-angiogenic and anti-apoptotic paracrine factors compared to BM-MSCs, AD-MSCs, and BM-MNCs.
In vivo, CDC-treated infarcted mice exhibited the greatest improvement in cardiac function, highest rates of cell engraftment and myogenic differentiation, the lowest apoptotic cell counts, and the least abnormal ventricular morphology.
Purifying the c-kit+ subpopulation from CDCs reduced paracrine factor secretion and yielded inferior functional recovery relative to whole, unsorted CDCs.
