Discovered to dissipate the dream of re-spending in people

The lizard's tail is not the perfect version of the original tail, a finding that can darken the hope of re-growing in humans.

The lizard's tail is not as good as the old tail

Researchers at the University of Arizona (USA) found key structural and structural differences when comparing the original tail and the tail that grew back in North American lizards.

It is also a common species of other lizards, able to shed its tail when pursued by enemies and then regrow new tails.

The team said that the reconstruction tail was supported by a long cartilage instead of the actual vertebrae in the original tail, and there were also muscle differences between them, according to a report on the NewScientist.com website.

Both of the main differences indicate that the tail regrow is not flexible with the original tail, according to University of Arizona researcher Rebecca Fisher.

Judging from the new research results, University of California expert Jason Pomerantz is pessimistic about the possibility of finding a way to re-create future human limbs.

'Even in the case that the regeneration is positive, the structure of that part is not perfect and the function does not keep up with the original parts , ' said Pomerantz.
