Will Humans One Day Regenerate Lost Limbs And Diseased Organs?
Growing a new body part comes naturally if you happen to be a starfish, salamander or certain kinds of lizard. Humans also have limited regenerative powers. For instance, the liver can regenerate itself after much of it has been surgical removed; the tips of injured fingers and toes can grow back under certain conditions; and our largest organ, the skin, regenerates itself roughly every month.
