"Cryopreservation" Natural Recordings by Native Speakers
Cryopreservation is the preservation of biological materials, such as cells, tissues, or organs, at extremely low temperatures, typically around -196°C, using liquid nitrogen or other cryogenic agents. The goal is to slow down the normal metabolic processes that occur in living cells, effectively putting them in a state of suspended animation, allowing for long-term storage and potential future use. This technique is commonly used in fields such as cryonics (the preservation of human bodies with the hope of future revival), stem cell banking, and fertility preservation.
Usage Examples for "cryopreservation"
Cryonic is a term that refers to the preservation of human bodies or heads at very low temperatures, typically around -196°C, with the hope that future medical technology will be able to revive them. The goal of cryonic preservation is to freeze the body or brain quickly enough to prevent cellular damage and decay, which would make revival impossible.
Cryopreserved refers to something that has been preserved or frozen at very low temperatures, typically using liquid nitrogen, in order to halt or slow down metabolic processes, such as biological or chemical reactions.
A cryoprotectant is a substance that helps to protect living cells or tissues from damage caused by the freezing process. It is often used to preserve cells, tissues, and organs for cryopreservation, which is a technique used to store biological materials at very low temperatures, typically around -180°C. Cryoprotectants work by reducing the formation of ice crystals within the cells, which can cause damage and death, by binding to water molecules and preventing them from freezing. Examples of cryoprotectants include sugars, polyols, and other solutes.
Cryosection refers to a technique in biology and medicine where a sample of tissue or organ is preserved by being rapidly frozen to very low temperatures, typically with liquid nitrogen, and then sectioned into thin slices using a cryotome (a special type of microtome). This technique is often used to study the microscopic structure of tissue and to examine the effects of disease, injury, or treatment on tissue.
