Frogs regrow amputated legs in breakthrough experiment
Scientists have regrown frogs’ amputated legs after giving them a “cocktail” of drugs encased in a silicon stump.
African clawed frogs (Xenopus laevis) are like humans in that they can’t naturally regrow lost limbs. In the new study, researchers successfully coaxed the frogs to grow replacement limbs in 18 months following a treatment that lasted just 24 hours. While there’s a massive difference between frogs and humans, the finding raises the possibility that in the future, humans could also regrow limbs.
