the quest to save human lives with organs from genetically modified pigs.

This time around, surgeons in Alabama transplanted a pig's kidneys into a brain-dead man -- a step-by-step rehearsal for an operation they hope to try in living patients possibly later this year.

"The organ shortage is in fact an UNMITIGATED CRISIS  and we've never had a real solution to it," said Dr. Jayme Locke of the University of Alabama at Birmingham, who led the newest study and aims to begin a clinical trial of pig kidney transplants.

After hearing this kind of research "had the potential to save hundreds of thousands of lives, we knew without a doubt that that was something that Jim would have definitely put his seal of approval on," said Julie O'Hara, Parsons' ex-wife.

Pig Kidneys Successfully Transplanted Into Brain-Dead Human Body

News of this development come shortly after surgeons in Maryland successfully performed a first-of-its-kind organ transplant of a genetically-modified pig heart into a human patient who was deemed too sick to qualify for a human heart.

"investigational" surgery is painless

As Locke's team reported in the American Journal of Transplantation, both kidneys survived with no signs of rejection for a little over three days, until the patient's body was taken off life support.

FWIW: I'm neither a pig nor a felon, but I've ticked the box since I first got a driver's license two states and 32 years ago despite reasonable fear that few of my organs are out-the-box, so to speak, "clinical-grade" A. Now, extrapolate: When the spirit is willing, but the flesh is weak, who is the injured party? Surgeons, drug manufacturers, epidemiologists, or GM pigs?
