Has anyone extended the time the frog remains frozen to see if it reanimates after a year, two years or 20 yeaers.
Several months in the winter might be its limit.
Combining frog DNA with human genes might create a mutant human who can live in or out of water and cryosleep for long space flights.
The bonus might be basketball superstars "swamping" the sport because of improved jumping ability.

Yes, but they'd never make it as attractive spokesmen because they'd be all warty and have a tendency to croak. *ribbit*
From what I have read, water seems to be the key, if the cells drop to less than 60% of their normal water level than the ice crystals that for naturally in the blood stream outside the cells begin damaging the cells and major organs.
You don't have to use the DNA; you need to duplicate the chemical and cooling process that happens naturally in the wood frog. This seems simple enough and straight forward when you are dealing with the organs rather than the entire body.
The problem seems to be getting enough glucose to each cell while bringing down the temperature to about -7 DEG C.
Unlike what we use to believe that you had to immediately cool the entire body or organ to a low enough temperature to prevent the ice crystals from forming (think -1000 DEG C) to prevent ice from crystallizing, these folks are doing the opposite. A gradual cooling to slightly below freezing while stuffing enough glucose to each individual cell thru ought the organ to prevent them from freezing.
