High pressure cryonics
One premise of the full proposal is that the freezing process should avoid the formation water crystals which prevent structural damage of membranes and proteins and keep the integrity of the life organism being frozen under high-pressure cryonics.

I have not seen a discussion on the thawing process which I always thought was a problem for example when thawing cells for in vitro cell culture.

For the design I would try small with for example mammalian cells like HeLa. Maybe full organisms like worms or flies for "tissues" and "full organisms".
