An injectable, bioresorbable electroactive device delivers VEGF-A mRNA via the pericardial space after mouse myocardial infarction, fully recovering stroke volume and ejection fraction.
- Why it matters: MI causes cardiomyocyte loss and remodeling that drives heart failure, but regenerative gene therapy has lagged clinically due to delivery limits that are targeted, minimally invasive, and scalable.
- What they did: The team built an in situ-forming conductive mRNA “drape” electrode that enables local electrotransfection over the injured heart and then bioresorbs, avoiding retrieval.
- The result: In mouse MI, localized VEGF-A mRNA delivery attenuated adverse remodeling and improved cardiac function, supporting a minimally invasive localized regenerative gene delivery strategy.
