Axolotl, or Mexican Salamander (IMAGE) MDI Biological Laboratory Caption The axolotl, or Mexican salamander, is one of the three regenerative species described in a new paper that identified common genetic regulators governing limb regeneration in all three species. The findings suggest that these regulators aren't specific to individual species, but have been conserved through evolution, including in humans. The discovery opens the door to being able to manipulate these regulators with drug therapies.
