grafts keep broken hearts from breaking rhythm
Researchers
have made a major advance in efforts to regenerate damaged hearts. They
discovered that transplanted heart muscle cells, grown from stem cells,
electrically couple and beat in sync with the heart’s own mucle.
The grafts
also reduced the incidence of arrhythmias (irregular heart rhythms) in a guinea
pig model of myocardial infarction (commonly known as a heart attack).
