What process involves the replacement of water in cells during cryopreservation?

• A. Cell lysis
• B. Dehydration
• C. Embedding
• D. Infusion

Answer: (B)

The process that involves the replacement of water in cells during cryopreservation is dehydration. In cryopreservation, maintaining the integrity of the cells and tissues is crucial, especially when exposed to extremely low temperatures. Water within cells can form ice crystals during freezing, which may cause cellular damage. Dehydration effectively reduces the intracellular water content, allowing for the replacement of water with cryoprotective agents, such as glycerol or dimethyl sulfoxide (DMSO). These agents help to protect the cells by preventing ice crystal formation and stabilizing cellular structures during the freezing and thawing processes. As a result, dehydration is a fundamental step in preparing cells for successful cryopreservation, enhancing their viability upon thawing and subsequent use.
