Krüokonserveeritakse

Krüokonserveeritakse refers to the process of cryopreservation, a technique used to preserve biological material by cooling it to very low temperatures, typically below -130 degrees Celsius. At these temperatures, biological activity, including the natural decay processes, is effectively stopped. This allows for the long-term storage of cells, tissues, organs, and even entire organisms without significant degradation.

The process involves carefully cooling the biological samples in the presence of cryoprotective agents. These agents, such as glycerol or dimethyl sulfoxide (DMSO), help to prevent the formation of damaging ice crystals within the cells during the freezing and thawing cycles. Specialized equipment is used to control the rate of cooling and warming, ensuring the viability of the preserved material.

Cryopreservation has a wide range of applications. In medicine, it is used for storing sperm, eggs, and embryos for fertility treatments, as well as for preserving stem cells for therapeutic purposes. It is also employed in research laboratories for maintaining cell lines and biological samples. In agriculture, it can be used to preserve seeds and genetic material from endangered plant species. The successful thawing and revival of cryopreserved material are crucial aspects of the overall process, requiring precise temperature control and often the removal of cryoprotective agents.
