American patent for a printer to print human tissue

Three-dimensional structure of tissues and organs reconstructed using three-dimensional printing, are U.S. inventor. He patented three-dimensional printer uses ink instead of living cells and their growth-regulating substances. Create a multi-layered structures in living cells at the Institute for Regenerative Medicine at Wake Forest University (North Carolina), James W (James Yoo) proposes to use an inkjet printer, so. The biological material on the basis of collagen fibers The printing process can also growth factors. Proliferation and differentiation, as well as special pigments that are used to regulate more intuitive spatial structure As stated in the patent, with the device already succeeded a few three-dimensional objects of different types of mammalian cells is obtained. In the future, a similar technique may be used to virtually every human tissue are new - from the skin to nerve, pancreas or bone safely Yu
