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 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.
Essentially, the idea is to make heart muscle cells, which have very little ability to regenerate, act more likeThe difference made by the mRNA treatment after four weeks. "When both transcription factors were injected into infarcted adult mouse hearts, the results were stunning,""The lab found cardiac myocytes multiplied quickly within a day, while hearts over the next month were repaired to near normal cardiac pumping function with little scarring."
