My understand has always been that ice crystal damage was the main limitation of cryopreservation. Successful vitrification exists in nature, but only in a few small animals. In many years of peripheral interest in the subject, I had never seen a clear explanation of why vitrified mammalian organs haven’t been reanimated. This seems like a very big deal. Has it been getting coverage?
