What happened if a tissue shows freezing artifact?

Freezing artifact happens when tissue is frozen too slowly. Water in the tissue forms large ice crystals, which swell and rupture cellular structures, producing distortions like broad spaces, cracks, and disrupted arrangement of cells and membranes. Rapid freezing minimizes crystal size, preserving architecture and reducing these artifacts, which is why slow freezing is the culprit here. Dehydration or excess fixative relate to other parts of tissue processing and don’t cause the classic freezing artifacts seen with ice crystal damage.
