Cryonic revival experiments will first be done on animals (hasn’t it been done with a mouse already?)
No one has revived a mouse. Kidneys have been done in rabbits. And we’ve also brought dogs down to low but slightly above freezing temperatures and brought them back with no substantial damage. But keep in mind that bringing something to the point of freezing in water is much higher temperature than liquid nitrogen and while kidneys have been brought to liquid nitrogen temperatures and back with minimal damage, kidneys are one of the simplest vital organs.
Reversible vitrification of major organs is a reasonable prospect within this decade. What about vitrification of whole animals? This is a much more difficult problem. Some organs, such as the kidney and brain, are privileged organs for vitrification because of their high blood flow rate. This allows vitrification chemicals to enter and leave them quickly before there are toxic effects. Most other tissues would not survive the long chemical exposure time required to absorb a sufficient concentration to prevent freezing.
I’m not too optimistic about reversal of full-body preservations performed in the next few decades. I am much more optimistic about prospects of regrowing the non-brain organs and creating a new body from them.

The brain and kidney do have similarities though.
