Once collected, the tissue sample undergoes several processing steps:
Fixation: The sample is preserved using a fixative, usually formalin, to prevent degradation. Embedding: The sample is embedded in a solid medium, typically paraffin wax, to facilitate sectioning. Sectioning: Thin slices of the embedded tissue are cut using a microtome. Staining: The tissue sections are stained to enhance the contrast and visibility of specific structures.
