Newt Finding Might Set Back Efforts to Regrow Human Limbs
Unique proteins in these amphibians cast doubt on the existence of any latent potential for limb regeneration
Moreover, Tanaka adds, scientists would do well to look for more grey zones in the potential for harnessing the regenerative capacities of newts (and of other animals, such as fish). Rather than focusing on spectacular, but perhaps unlikely, scenarios in which amputees could regrow entire limbs, researchers should instead focus on more plausible options, such as improving the healing of scars and burns or increasing the speed of organ regeneration.
