Cryopreservation Techniques

Cryopreservation is a method used to preserve biological materials by cooling them to very low temperatures, typically using liquid nitrogen. This process slows down cellular metabolism and stops all biochemical reactions, effectively pausing biological activity. Cells, tissues, or even whole organisms can be preserved for long periods without damaging their structures. Common applications include preserving sperm, eggs, and embryos for fertility treatments, as well as storing stem cells for research and medical treatments. By carefully controlling the freezing and thawing processes, scientists ensure the viability of the preserved materials upon revival.
