Ordinary freezing damages tissue with ice crystals. Vitrification attempts to turn water and solution into a glass-like state without large crystals.
This requires cryoprotectants, controlled cooling, and toxicity checks. In practice, it is a tradeoff between less ice damage and chemical load.
That is why Gelyrix talks not only about storage, but also about checks: microscopy, damage markers, and functional reversibility tests where possible.
