These are the days of Miracle and Wonder

Spare parts are available for virtually any machine ever invented. So why not the human body? San Diego–based companies Invetech and Organovo have developed what amounts to a dot-matrix printer for human organs. The device, small enough to fit into a sterile biosafety cabinet, consists of two printheads — one that sprays out a gel that forms a sort of armature for an organ and another that fills in that scaffolding with living cells. The printing tip positions cells with a precision within microns. Livers, kidneys and other replacement components — including teeth — could be built on demand, with no wait for a donor and less risk of rejection, since the cells are harvested straight from the patient. No word yet on a parts-and-labor warranty.,28804,2029497_2030617_2029812,00.html
