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
