Human heart cells and tissues grown in the laboratory from stem cells promise to accelerate the development of drugs and treatments for heart disease, but they currently take weeks or months to grow.

Researchers have shown that cardiac scar tissue (fibroblasts) can be directly reprogrammed to heart muscle cells (cardiomyocytes) in mice. By treating mice post-heart attack with a virus carrying ...

When someone suffers a heart attack, their heart is left permanently scarred and thus less capable of pumping blood. According to a new study, however, a protein injection could help undo such damage.
