A team at the University of Cambridge reported that an experimental mRNA therapy, injected into the hearts of mice after a heart attack, prompted heart muscle cells to divide and raised the blood pumped per beat by about 10% compared with mock treatment. The improvement persisted at 28 days and at 12 weeks, according to the study in Nature Cardiovascular Research. Further trials in larger animals and in humans are needed.
