Inhalable exosomes to target cardiac repair.

A recent study introduces Stem Cell-derived Exosome Nebulization Therapy (SCENT), a novel, non-invasive strategy that delivers lung spheroid cell-derived exosomes via inhalation to promote cardiac repair after myocardial infarction. This approach improves cardiac function, reduces injury, and demonstrates translational potential in both small and large animal models, offering a promising avenue for cell-free, inhalable regenerative therapies.
