Sustained miRNA delivery from an injectable hydrogel promotes cardiomyocyte proliferation and functional regeneration after ischaemic injury

MicroRNA-based therapies that target cardiomyocyte proliferation have great potential for the treatment of myocardial infarction. In previous work, we showed that the miR-302/367 cluster regulates cardiomyocyte proliferation in the prenatal and postnatal heart. Here, we describe the development and application of an injectable hyaluronic acid hydrogel for the local and sustained delivery of miR-302 mimics to the heart. We show that the miR-302...
