Living Organs Produced by 3D Printers
Gizmodo has the story on this:
For the first time ever, scientists are successfully 3D printing actual, living human kidneys. Like the human livers printed in the past, the kidney are currently miniature in size, but with about 90% of the printed cells being alive, the potential for human use looks immensely positive.The progress in this area has been phenomenal. A few years ago 3D printers were being used to make organ casings and other related structures. Now they are producing living tissues which actually could perform the function of the full organ. They are a bit small yet and still not quite ready to be transplanted into a host who needs the full-sized model, but stay tuned.
