“The researchers [at Duke University] formulated a cocktail of RNAs and packaged them into exosomes, a natural product produced by most cells. This technology allowed them to deliver the exosomes without surgical interventions. Exosome packages have unique properties that guide them to cardiac fibroblasts inside an injured heart.” MORE
