Adult stem cells may help repair hearts, study finds

Adult stem cells might help repair hearts damaged by heart attack — in part by becoming heart cells themselves. That was the finding of a new study, released Monday, that points to a promising new treatment for heart-attack patients that could reduce mortality and lessen the need for heart transplants. Adult stem cells also could help heal livers, kidneys, pancreases and other organs.
