Key to lost limbs lurks in DNA

If a zebrafish loses a part of its fin, regeneration genes will kick in to regrow the tissue that was injured.

Researchers at Duke University have now uncovered the mechanism that activates these genes, to better understand what drives regeneration.

These newfound ‘enhancer elements’ could be used to help mammals, including humans, regrow body parts, the researchers say.
