Updated project metadata. Secretome containing extracellular vesicles (EV) seem to mediate the benefits of cell therapy for ischemic heart failure. Our project has the objective of comparing the secretome containing extracellular vesicles (EV) from cardiac progenitor cells (EV-CPC) vs the secretome containing EV from Fibroblasts (EV-FB) in order to stablish a protein cartography of EV-CPC and the biological pathways that they are involved. seem to mediate the benefits of cell therapy for ischemic heart failure.
