Regenerative medicine worksMikey 5 comments
As incredible as it sounds, a man was able to grow back his finger, vessels flesh and nail, in only 4 weeks after it was cut off by a model airplane propeller.
Lee Spievack's brother, a medical research scientist, gave him a special powder to sprinkle on the wound, which grew the finger back. The powder is made from pig bladders called extracellular matrix. It is a mix of protein and connective tissue surgeons often use to repair tendons and it holds some of the secrets behind the emerging new science of regenerative medicine.
Wait for the video after the ad break.
