Scientists have developed a new technique that can repair and even regenerate heart muscle cells after a heart attack (or myocardial infarction).
While it has only been tested on mice so far, if it works the same in humans it could potentially be a life-saving treatment for people who have suffered a heart attack.
The technique uses a synthetic messenger ribonucleic acid (mRNA). mRNA creates a ‘blueprint’ of DNA sequences that the body then uses to build the proteins that form and regulate our cells. By tweaking the mRNA, scientists can deliver different instructions for different biological processes.
