Mayo Clinic researchers say they have genetically engineered cells that help transform scar tissue into a type of cell that helps the heart repair itself after a heart attack.

They then put these iPS cells into the damaged hearts of mice. After four weeks, the mice hearts had improved structure and function, the scientists say. Investigators believe their finding shows the potential for using iPS cells in cardiac treatment.  Read full story >
