Can science unlock in humans the ability to regenerate like the Mexican salamander?

Michael D. West, Ph.D., CEO of AgeX Therapeutics, discusses the emerging field of regenerative medicine. He uses the example of how the Mexican salamander can re-grow limbs and even organs. By studying how Mexican salamanders regenerate, Dr. West posits that researchers can learn how to harness the same power in humans. Humans, Dr. West points out, are born with the ability to completely regenerate until eight weeks after conception. Humans lose that ability, but Dr. West says scientists will someday be able to regenerate cells in the human body much like the Mexican salamander does today.
