Regeneration is a trick many animals, including lizards, starfish, and octopuses, have mastered
Axolotls, a salamander species originating in Mexico, can regrow pretty much everything from severed limbs, to eyes and parts of brain, to
Mammals, though, have mostly lost this ability somewhere along their evolutionary path
certain animals lost their regeneration capacity during evolution and then put back the responsible gene or pathway to reactivate the
did not have it before.The idea Wang and his colleagues had was a comparative study of how the wound healing process works in regenerating
and non-regenerating mammalian species
They chose rabbits as their regenerating mammals and mice as the non-regenerating species
As the reference organ, the team picked the ear pinna
The test involved punching holes in the ear pinna of rabbits and mice and tracking the wound-repairing process.The healing process began in
the same way in rabbits and mice
In mice, on the other hand, the healing process halted completely, leaving a hole in the ear.
