Study finds stem cells repair damaged heart tissue

The Miami Herald reports that in a University of Miami/Johns Hopkins University study, heart-attack patients who received direct injections of stem cells to their damaged heart muscles were found to have reduced scar tissue and other improvements -- even decades after a heart attack.

According to the report: 

The study, which was funded by the National Institutes of Health and published in the Journal of the American Medical Association this week, found that stem cell injections into the heart muscle reduced scar tissue by one third, built up healthy heart tissue and remodeled the spherical shape of the damaged heart to look more like a football-shaped healthy heart.

Note: Dr. Joshua Hare, the leader of the stem cell study, will speak in Ann Arbor  on April 29, 2013, as part of the Taubman Institute's Visiting Professor Lecture Series and the U-M Health System's Frontiers in Cardiovascular Science seminars.
