“Australian researchers have isolated an immune system cell in salamanders which helps it regenerate missing limbs and damaged organs — and they suspect the same thing could work in humans, too.

Salamanders, or axolotls, are unique among vertebrates in that they’ve got remarkable regenerative powers. Adults can literally regrow and restore function to any part of the body, including the spinal cord and heart — even parts of the brain. Moreover, the regenerated tissue is scar free; once repaired, the new tissue looks almost the same as it was before.” More info: http://bit.ly/13K8vhx
