University of Washington researchers find that human derived stem cells can repair rat hearts damaged by heart attack

When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal's heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. The researchers also developed a new process that greatly improves how stem cells are turned into heart muscle cells and then survive after being implanted in the damaged rat heart. The findings suggest that stem-cell-based treatments might one day help people suffering from heart disease, the leading cause of death in most of the world.
The study was conducted by researchers at the University of Washington School of Medicine in Seattle and at Geron Corp. in Menlo Park, Calif. The scientists set out to tackle two of the main challenges to treating damaged hearts with stem cells: the creation of cardiac cells from embryonic stem cells, and the survival of those cells once they are implanted in a damaged heart.
