cryopreservation
definition: Cryopreservation, which derives from the Greek word cryo for “icy cold,” is a process whereby cells and sometimes whole tissues are preserved by cooling to very low subzero temperatures, often 77 K or minus 196 degrees C, the boiling point of liquid nitrogen. This is because at these very low temperatures any biological activity is effectively stopped, including those biochemical reactions that might lead to cell death.
