Tinkering with microRNAs helps heart cells regenerate

Scientists and cardiologists have known for decades that once a piece of heart muscle has died, for example due to a heart attack, it will never grow back. This is because an adult heart muscle cell is not able to divide in the way a skin cell does to repair a wound. However, a research group from Maastricht University led by Professor Leon de Windt has now shown that by tinkering with microRNAs, heart muscle cells can indeed be prompted to regenerate. The research was published earlier this month in Nature Communications.
