I have found an interesting article about reprogramming cells about to become scar tissue in mice that have suffered a heart attack:

Reversing a heart attack: scientists reprogram scar tissue into working muscle

http://blogs.scientificamerican.com/science-sushi/2012/04/18/reversing-a-heart-attack-scientists-reprogram-scar-tissue-into-working-muscle/

"The researchers were able to use a virus-based system to deliver three key genes that guide embryonic heart development—Gata4, Mef2c and Tbx5 (GMT)—to areas of mouse hearts that were damaged in a heart attack. Within a month, cells that normally became scar tissue were beating away again as if they were not knocking on death’s door just 30 days before."

I don't think this works on already existing scar tissue just tissue that is about to scar but I should look into this further.
