Progress on the road to regenerating major body parts, salamander-style, could transform the treatment of amputations and major wounds

* The gold standard for limb regeneration is the salamander, which can grow perfect replacements for lost body parts throughout its lifetime. Understanding how can provide a road map for human limb regeneration. * The early responses of tissues at an amputation site are not that different in salamanders and in humans, but eventually human tissues form a scar, whereas the salamander’s reactivate an embryonic development program to build a new limb. * Learning to control the human wound environment to trigger salamanderlike healing could make it possible to regenerate large body parts.

A salamander’s limbs are smaller and a bit slimier than those of most people, but otherwise they are not that different from their human counterparts. The salamander limb is encased in skin, and inside it is composed of a bony skeleton, muscles, ligaments, tendons, nerves and blood vessels. A loose arrangement of cells called fibroblasts holds all these internal tissues together and gives the limb its shape.

Well, Obama is trying to move the foot that keeps regenerating out of his mouth.

I think his pastor stuck it up his a$$ for safe keeping
