Mexican Salamander Regenerates Body Parts



Axolotl - Ambystoma mexicanum
(Hanover, Germany) An unusual salamander has abilities that scientists want to understand.

The axolotl is one of a kind in nature: It can regenerate severed limbs, organs and even grow back its spinal column after injuries. At a new research center in Hanover, Germany, researchers are trying to unlock the Mexican salamander's secrets -- and whether they can be applied to humans.

They appear to be quite content. Around 100 salamanders are bobbing around in the aquarium at the Hanover Medical School in Germany. Their brachial gills sprout like hair from their heads and their tiny mouths seem to smile as they press their tiny front feet against the sides of the aquarium.

They don't all look the same, however: Some are missing an arm or a leg; others have a stump where a limb is in the process of growing back.

These are no ordinary amphibians. Many have had flaps of skin removed or parts of their limbs cut off -- under sedation of course -- by scientists investigating their regenerative capabilities.

Cute little thing, ain't it?
