We've been growing skin (from somatic skin cells) in dishes for years. Organovo's 3-D printed kidneys (made from somatic kidney cells) are from last April, although there had been earlier attempts, and 3-D printed kidneys have been implanted into living patients now. 3-D printed bones are from 2010, because it's adequate to print a mineral "skeleton" that living cells then colonize after implantation.
