Hypothermic preservation is a technique used to store biological tissues, organs, or cells at low temperatures to slow down metabolic processes. This method helps to maintain the viability of these biological materials for extended periods, making it crucial in fields like organ transplantation and cell therapy. By reducing the temperature, the activity of enzymes and other cellular processes is minimized, which helps prevent damage. This preservation technique is often employed in conjunction with cryopreservation, where samples are frozen for long-term storage. It is also essential in the transportation of organs for transplant, ensuring they remain functional until they reach the recipient.
