cryopreservation

The reversible freezing of tissues–eg, packed RBCs and pre- and post-fertilization products, and autologous BM, often with glycerol for autologous BMT Reproduction medicine A technique for freezing cells to preserve for later use. See Frozen cells, in vitro fertilization.

During cryopreservation, the samples survival will depend on the glassy state of explants, that is, the direct transition of water from liquid to an amorphous or glassy solid (Engelmann, 2011).
A further advantage of cryopreservation over conventional storage techniques is that once in cryogenic storage there is virtually no risk of new microbial contamination and the development of disease.
