What is the Difference Between Slow Freezing and Vitrification?
Both slow freezing and vitrification are methods used to preserve biological tissues, but they differ significantly in their approaches. Vitrification involves ultra-rapid cooling, which prevents the formation of ice crystals by turning the sample into a glass-like state almost instantly. This method is often preferred for oocytes and embryos due to its higher survival rates post-thaw. However, slow freezing remains a reliable option for certain types of tissues, such as ovarian tissue.
