Cryopreservation is the process of preserving living cells and tissues at low temperatures. Synonyms for cryopreservation include cryogenic preservation, low-temperature storage, frozen preservation, and cryostorage. These terms are often used interchangeably but have some nuances in meaning. Cryogenic preservation implies the use of extremely low temperatures, while low-temperature storage refers to any temperature below freezing. Frozen preservation is a more general term that can refer to any method of preserving in a frozen state, including without the use of cryoprotectants. Cryostorage is a specific type of cryogenic preservation that involves the use of a cryostat to maintain a constant low temperature. Overall, these synonyms demonstrate the range of techniques and applications for preserving biological materials using low temperatures.
