How to repair a damaged heart: key mechanism behind heart regeneration in zebrafish revealed
Cardiovascular diseases, such as heart attacks, are a leading cause of death worldwide resulting from a limited self-healing power of the heart. Unlike humans, zebrafish have the remarkable capacity to recover from cardiac damage. Researchers from the group of Jeroen Bakkers (Hubrecht Institute/ UMC Utrecht) have used the zebrafish to shed light on their regenerative success. They discovered a new mechanism that functions as a switch to push the heart muscle cells to mature in the regeneration process. Importantly, this mechanism was evolutionary conserved as it had a very similar effect on mouse and human heart muscle cells. The results of the study, published in Science on May 18th, show that examining the natural heart regeneration process in zebrafish and applying these discoveries to human heart muscle cells could contribute to the development of new therapies against cardiovascular diseases.
