Scientists are closing in on ways to help patients grow new heart muscle after a heart attack, as well as new lung tissue to treat fibrosis, corneas to erase eye pain and other body parts to gain a new chance at life.

If the science works, it could represent a new approach to medicine: reversing rather than alleviating chronic illnesses.”
