Visualization of heart regeneration in adult zebrafish. After injury the heart activated factors, such as epicardial IGF, able to activate the Ras/MAPK pathway. These activated epicardial cells drive cardiomyocyte regeneration after injury and are essential for cardiomyocyte proliferation in heart regeneration.
