Since cancers tend to evolve heavily, this might be a way of
discovering genes useful for cryopreservation. Just freeze a cultured
tumour, unthaw it, let the surviving cells divide, freeze again, and
so on. Eventually you would evolve tumour cells that could deal with
freezing quite well, and you could start looking for the genes
involved. The hard part is to do this in vivo rather than in vitro,
since we want cryoprotectant mechanisms that work on tissues rather
than single cells.
