While therapies to stimulate and harness this repair mechanism are still in laboratory development, the discovery confirms that damaged cardiac tissue is not biologically doomed to permanent scarring. It opens an entirely new therapeutic horizon focused on helping the body repair itself rather than simply managing chronic failure.
