Scar tissue turned into heart muscle without using stem cells

Scientists at Duke University Medical Center have shown the ability to turn scar tissue that forms after a heart attack into heart muscle cells using a new process that eliminates the need for stem cell transplant.

Finding suggests ways to promote adult heart tissue regeneration

Injured hearts do not heal themselves. Heart muscle cells, or cardiomyocytes, do not proliferate as much as necessary to replace dead tissue with new, pumping cells. Consequently, most people who had a severe heart attack ...

Stem cells boost heart's natural repair mechanisms

Injecting specialized cardiac stem cells into a patient's heart rebuilds healthy tissue after a heart attack, but where do the new cells come from and how are they transformed into functional muscle?
