Behold "the world's first production model 3D bio-printer." A machine capable of arranging human cells and artificial scaffolds into complex three-dimensional structures, which result in such wonderful things as printed design meat, replacement organ tissue, or perhaps artificially grown teeth. "Scientists and engineers can use the 3D bio printers to enable placing cells of almost any type into a desired pattern in 3D," says Keith Murphy, CEO of Organovo – the San Diego based company who will supply the devices institutions investigating human tissue repair and organ replacement. "Researchers can place liver cells on a preformed scaffold, support kidney cells with a co-printed scaffold, or form adjacent layers of epithelial and stromal soft tissue that grow into a mature tooth. Ultimately the idea would be for surgeons to have tissue on demand for various uses, and the best way to do that is get a number of bio-printers into the hands of researchers and give them the ability to make three dimensional tissues on demand." Building human organs cell-by-cell was considered science fiction not that long ago, but now rapidly becomes science faction. Yet another step in the blending of the 'made' and the 'born'.
