What you’re looking at is a picture of a tadpole’s tail. The tail of this tadpole was regenerated after 18 hours after being cut by an hours long exposure to a Sodium Ion cocktail.

The frog tail is a good model for human regeneration because it repairs injury in the same way that people do: each tissue makes more of itself. (In contrast, regeneration in some other animals occurs through transdifferentiation (one cell type turns into another cell type) or adult stem cell differentiation.  Furthermore, though small, the Xenopus larval tail is complex, with muscle, spinal cord, peripheral nerves and vasculature cells.

There are some interesting realizations. This means the injuries are theoretically capable of regenerating after they have been healed.  Since this tadpole uses the same type of cellular regeneration that we do it is even more feasible. Lastly, This isn’t just a bunch of skin cells or similar muscle cells we are talking complex regeneration and the limb didn’t grow abnormalities. No gene therapy was needed and no stem cells were hurt in the regenerations of these limbs. Astounding.
