Perry, Are you sure about this. I was under the impression that Greg Fahy had been able to perfuse rabbit kidneys with a level of cryoprotectant that WOULD ALLOW vitrification and then recover those kidneys (flush the cryo- protectant) and show that they were functional (through transplantation?), but that he had NOT actually vitrified them. Could someone shed some light on this? Mike --- Micheal B.
