At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
[2] Genetic materials that are typically cryogenically preserved include sperm, oocytes, embryos and somatic cells. [3] [4] Cryogenic facilities are called gene banks and can vary greatly in size usually according to the economic resources available.
Cryopreservation or cryoconservation is a process where biological material - cells, tissues, or organs - are frozen to preserve the material for an extended period of time. [1] At low temperatures (typically −80 °C (−112 °F) or −196 °C (−321 °F) using liquid nitrogen ) any cell metabolism which might cause damage to the biological ...
An example of one of the world’s largest animal cryobanks is the frozen zoo made by the San Diego Zoo, in San Diego California. [8] With animal cryobanks freezing embryos is preferred instead of the separate egg and sperm because the embryos are more resistant to the freezing process. [9] USDA cryopreservation gene bank
In 2016, McIntire and Fahy were awarded the first portion of the Brain Preservation Technology Prize, the Small Animal Brain Preservation Prize, by the Brain Preservation Foundation for the successful cryopreservation of a whole mouse brain. [2] [3] The cryopreserved brain was rewarmed and no serious degradation was found to have occurred; the ...

A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants (antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods.
