cryopreservation

Definitions

from Wiktionary, Creative Commons Attribution/Share-Alike License

  • n. the preservation of biological tissue at cryogenic temperatures, typically at -80°C (dry ice temperature) or -196°C (the boiling point of liquid nitrogen).

Etymologies

cryo- +‎ preservation, from Ancient Greek κρύος (kruos, "icy cold, chill, frost"). (Wiktionary)

Examples

  • While still experimental, ovarian tissue cryopreservation is beginning to show promise as a viable clinical option.

    Fertility Therapies

  • While it was once necessary for the menstrual cycles of both donor and recipient to be carefully coordinated—her eggs had to be ready to ovulate at the precise time your uterus was ready to accept an embryo—this is no longer necessary, thanks to an innovation called cryopreservation, or embryo freezing.

  • "The freezer could be the future for frogs and other amphibians. Efforts announced today are currently underway around the world to boost amphibian numbers with cryopreservation and assisted reproduction.
    Breeding frogs and their cousins to increase numbers could help vulnerable species survive looming extinctions. But getting amphibians to mate is not always straightforward, so researchers are developing other techniques to give them a helping hand."

  • A process where cells or whole tissues are preserved by cooling to low sub-zero temperatures. At these low temperatures, any biological activity, including the biochemical reactions that would lead to cell death, is effectively stopped. From the field of Cryonics. (Wikipedia)
