While a number of vertebrates, including fishes, salamanders, frogs, and lizards, display regenerative capacity, the process is not necessarily the same. It has been proposed that regeneration, while evolutionarily conserved, has diverged during evolution. However, the extent to which the mechanisms of regeneration have changed between taxa still remains elusive. In the salamander limb, cells dedifferentiate to a more plastic state and aggregate in the distal portion of the appendage to form a blastema, which is responsible for outgrowth and tissue development.
