There is accumulating evidence that the cardioprotective effects of stem cells are predominantly mediated by the release of a blend of factors, possibly clustered into extracellular vesicles, which harness endogenous repair pathways. The clinical translation of this concept requires the identification of the cell-secreted signaling biomolecules and an appropriate transfer method. The study by Wei and colleagues has addressed these 2 requirements by showing that the epicardial delivery of a collagen patch loaded with the cardiokine follistatin-like 1 improved left ventricular function in animal models of myocardial infarction. Beyond the choice of the factor and its vehicle, these data may open a new therapeutic path whereby the functionalization of biomaterials by bioactive compounds could successfully substitute for the current cell transplantation-based strategy.
