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 ...
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.
There have been difficulties using particular methods of cryoconservation with certain species. For example, artificial insemination is more difficult in sheep than cattle, goats, pigs, or horses due to posterior folds in the cervix of ovines. [13] Cryopreservation of embryos is dependent on the species and the stage of development of the embryo.

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.
A company called Tomorrow Biostasis is focusing on human cryopreservation in the hopes it can eventually reverse death.. The new Berlin startup has already preserved the bodies of about 10 ...
A cryopreservation straw is a small storage device used for the cryogenic storage of liquid samples, often in a biobank or other collection of samples. Their most common application is for storage of sperm for in-vitro fertilization.
Cryonics, the storage of human remains using cryopreservation; Embalming, the preservation of human remains by treatment with chemicals; Mummification, the preservation of humans or animals by removing all moisture from the body; Plastination, a technique used in anatomy to preserve bodies or body parts, developed in 1977
