Matt Ridley's article in the Wall Street Journal (July 16, 2011) begins with a mention of a synthetic windpipe grown with the patient's own cells. It was then successfully implanted in the patient, and he went home. (I've seen other accounts of this particular operation, and will include them here another time.)
Meanwhile, Dr. Anthony Atala at Wake Forest University is experimenting with "printing" whole kidneys, using something akin to an ink-jet printer. The procedure is still experimental and not able to turn out actual usable human kidneys, just replicas. But the time will come.
As I've written elsewhere on this blog, the concepts I put forth in the early version of my sci-fi thriller, THE LIFE AFTER LIFE CONSPIRACY, were rejected by the publishing powers-that-be (rather "powers-that-were") as, paraphrasing, "too far out, impossible, just not ever going to happen." Well, that was then, and a lot of it is happening around us now . . . though not yet the "Vehicles."
