Heart muscle can regenerate itself in very limited amounts, scientists find

UCLA researchers are first to directly measure division of cardiomyocytes

Researchers from UCLA’s Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research are the first to directly measure the division of heart muscle cells, proving that while such division is very rare, it does occur.

The study, conducted by assistant professor of cardiology Dr. Reza Ardehali and colleagues, resolves a recent controversy over whether the heart muscle has the power to regenerate itself. The findings are also important for future research that could lead to the regeneration of heart tissue to repair damage caused by disease or heart attack. (more…)

Muscle Cell 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).

This finding from University of Washington-led research is reported in the Aug. 5 issue of Nature. (more…)
