I came across an article about tissue manufacturing, while we have been recreating different body parts, this is in a new way, with a 3D printer. They are creating capillaries with a printer in this lab, capillaries have proven to be an issue in building larger structures in the past so this is their way around it. While it is a while out, if not impossible for large complex organs to be transplanted into humans, it is being seen as a way to test new drugs on artificial organs, rather than go through the human testing as in The Immortal Life of Henrietta Lacks. What do you guys think of tissue manufacturing? How about the manufacturing of entire organs?
