Humans may have hidden regenerative powers

Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring bone, joints, ligaments, and tendons after amputation in animal studies.

This approach has significant implications for the treatment of amputations and other injuries, and may provide new avenues for the development of regenerative therapies.
