It seems that they can use vitrification as opposed to solely freezing the body, and this is more effective at preservation. Here’s a paper about scientists vitrifying a rabbit kidney then rewarming it and successfully putting it back into a rabbit (h/t wait but why). However, it seems that each organ must be studied so that it can be successfully vitrified given its unique complexities, so we can’t just apply that paper’s solution to every organ.
