Scientists will look to test the method on mammals next.
Scientists have successfully re-grown a frog's missing leg in what's being described as a "significant advancement" for regenerative medicine.
The frog was treated with a cocktail of drugs for just 24 hours and within 18 months had regrown a fully functional leg.
Scientists will look to test the method on mammals next, verging closer still to the ultimate goal of human limb regeneration.
