Exosome spray helps with heart repair in rats after myocardial infarction

Written by Sharon Salt

Despite the improvements made in modern surgical techniques, diagnostics and medications for myocardial infarction, many individuals still struggle with the long-term effects of tissue damage. Now, researchers have developed a minimally invasive exosome spray that helped repair rat hearts after myocardial infarction. Stem cell therapy has been explored as an avenue to regrow tissue after a heart attack. However, introducing stem cells directly to the heart can be risky because they could trigger an immune response or grow uncontrollably, which can subsequently result in a tumor. In this study, which has been published in ACS Nano, researchers tried injecting mesenchymal...
