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. At low temperatures (typically −80 °C (−112 °F) or −196 °C (−321 °F) using liquid nitrogen) any cell metabolism which might cause damage … See more Tardigrades, microscopic multicellular organisms, can survive freezing by replacing most of their internal water with a sugar called trehalose, preventing it from crystallization that otherwise damages cell membranes. … See more Storage at very low temperatures is presumed to provide an indefinite longevity to cells, although the actual effective life is rather difficult to prove. Researchers … See more The main techniques to prevent cryopreservation damages are a well-established combination of controlled rate and slow freezing and a newer flash-freezing process … See more Bacteria and fungi can be kept short-term (months to about a year, depending) refrigerated, however, cell division and metabolism is not completely arrested and thus is not an optimal option for long-term storage (years) or to preserve cultures genetically or … See more One early theoretician of cryopreservation was James Lovelock. In 1953, he suggested that damage to red blood cells during freezing was due to osmotic stress, and that increasing … See more Phenomena which can cause damage to cells during cryopreservation mainly occur during the freezing stage, and include solution effects, extracellular ice formation, dehydration, and intracellular ice formation. Many of these effects can be reduced by cryoprotectants. … See more Generally, cryopreservation is easier for thin samples and suspended cells, because these can be cooled more quickly and so require lesser doses of toxic cryoprotectants. … See more http://longevityfacts.com/cryonics-cryogen-cryopreservation-freeze-body-death-pay-new-blockchain-based-cryptocurrency/
