Newt Limb Regeneration

This is part of: Potent Biology: Stem Cells, Cloning, and Regeneration


Urodele amphibians—newts and salamanders—are able to regenerate fully functional limbs in response to amputation. Cells in and near the limb stump dedifferentiate to form a mass of stemlike cells that can produce all the specialized tissues of the limb, such as muscle, nerves, and blood vessels.
