This also leads to new questions about the history of these capabilities, and the possibilities for the future. Is curing your stiff joints worth taking a risk with gene therapy? Geckos, salamanders, and anoles can all lose their tails and regrow them. In this case, taking a leap of faith with an experimental new treatment based on lizard genes might seem like an attractive prospect. Theoretically, we may be able to study the genetic makeup of these animals and develop treatments that could mimic some of their regenerative abilities. After analyzing the genetic makeup of various lizards, researchers were able to isolate a group of 326 genes that “lit up” when tail regeneration took place. Did you know you can regrow fruit at home?! Now, a study has found that American alligator ( Alligator mississippiensis ) can indeed re-grow their lost tails.

The real regenerative animal though comes from the amphibians, salamanders and newts can regrow entire limbs complete with new bones and nerve endings. As kids, all of us have learnt that smaller reptiles, such as lizards, can regrow their tails within days. Within the lizard’s genes themselves was the instructions for regeneration. The lizard can always regrow a tail, but they are not in good health after losing it. In addition to previous studies about the ability of lizards to regrow their tails, the discovery of such large and complex new tails in alligators provides considerable new information about regenerative process in the larger animal classification of amniotes. All Of The Tails After researching hundreds of lizards across various species, scientists discovered that two tails can sprout during the regrowth period, rather than just one. This research was funded by support from The College of Liberal Arts and Sciences at ASU. "What makes the alligator interesting, apart from its size, is that the regrown tail exhibits signs of both regeneration and wound healing within the same structure," said Cindy Xu, a recent PhD graduate from ASU's School of Life Sciences molecular and cellular biology program and lead author of the paper.

Lizards’ tails also contain a lot of nutrients and fat (in some lizards) required for the wellbeing of your pet. Agamid lizards often don't share that trait). In addition, many species of lizards such as Plestiodon fasciatus, Cordylosaurus subtessellatus, Holaspis guentheri, Phelsuma barbouri, and Ameiva wetmoreihave elaborately colored blue tails which have been shown to divert pred… Bigger animal takes longer to regrow its tail. On the other hand, what if you had suffered a serious spinal injury? Many kinds of small reptiles, such as lizards, are known to regrow their tails. They theorized that regeneration would take place only on the tip of the tail, but discovered instead that genes were being “turned on” throughout the muscles, cartilage, and the spinal column of the entire limb. While much smaller reptiles such as lizards are able to regenerate their tails, the question of whether the much larger alligator is able to regrow their massive tails has not been well studied. Within reptiles, several species can regrow their tails, but these replacements aren’t always as good as the originals.
