Laboratory-grown human skin is developed in Boston.

[1984] The first use of laboratory-grown human skin, it is used to treat two brothers, who were badly-burned in a fire in Wyoming. The skin is grown in large sheets from samples taken from two young men then grafted back onto their bodies. Both live for another 20 and die from complications not related to their burns. The procedure was developed by Dr. Howard Green and others at Harvard Medical School in 1972 and enables skin replacement surgery on patients with severe burns.
