Drug Cocktail Makes Frog Amputee Regrow Limb

The technique used, which was developed at Wyss and Tufts University, involves applying a cocktail of 5 drugs to the frog’s stump before sealing it with a small silicone dome. Although the cocktail is only applied for 24 hours, after 18 months, the frog had developed a limb that could respond to touch, and help the amphibian swim. The limb also grew several toes, but sans webbing between them. The breakthrough brings the team a step closer to achieving regenerative medicine, or at the very least a more sustainable approach to the culinary frog leg industry.
