Instead they applied extracellular vesicles -- a small structure within a cell -- secreted by cardiomyocytes, which make up the cardiac muscle cells.Their findings were published Monday in the journal Nature Biomedical Engineering."We reasoned that the cardiomyocytes would be the best source of molecules driving the recovery of injured heart, as it is well known that the...
