Stem cells can help repair severely damaged bones quickly, studies on sheep and humans have revealed.
Mice lacking the p21 gene can be healed scar free, a study has shown.
Newborn mice can regenerate their own heart tissue following heart damage.
Understanding regeneration in model organisms gives hope that it may one day be possible for amputees to regrow limbs, or for heart attack patients to regrow healthy heart muscle.
