BACKGROUND: Exosomes derived from mesenchymal stem cells (MSCs) were proved to
boost cell proliferation and angiogenic potency. We explored whether cardiac stem
cells (CSCs) preconditioned with MSC exosomes could survive and function better
in a myocardial infarction model. METHODS AND RESULTS: DiI-labeled exosomes were
internalized with CSCs. They stimulated proliferation, migration, and angiotube
formation of CSCs in a dose-dependent manner. In a rat myocardial infarction
model, MSC exosome-preconditioned CSCs had significantly better survival,
enhanced capillary density, reduced cardiac fibrosis, and restored long-term
cardiac function. MicroRNA profiling analysis revealed that a set of microRNAs
were significantly changed in CSCs after MSC exosome treatment. CONCLUSIONS:
Pretreatment of CSCs with MSC exosomes provided a promising strategy to improve
survival and angiogenic potency of CSCs.
