   Frogs Regrow Missing Limbs in Lab Study, Advancing Key Effort of   
   Regenerative Medicine   
      
   Amphibians developed leglike appendages within 18 months after brief   
   treatment with five-drug 'cocktail'   
      
   Salamanders do it. So do starfish. And now scientists have shown that   
   frogs can regenerate amputated limbs, once their stumps have been   
   treated with a multidrug "cocktail." The findings, published Wednesday   
   in the journal Science Advances, represent a notable advance in the   
   field of regenerative medicine, which aims to replace human tissues   
   and organs to restore normal function.
