Old hearts made young by natural substance
Old hearts can be made young again—at least in mice, Harvard researchers find.
In mice as in men, the heart muscle becomes thicker and stiffer with age. It's the most common cause of heart failure, yet there are no specific treatments.
Now it appears that a natural substance can reverse this aging process, according to a report in the May issue of the journal Cell by a team led by Dr. Richard Lee, co-editor in chief of the Harvard Heart Letter, and Amy Wagers, professor of stem cell and regenerative biology at Harvard Medical School.
