Sample Collection: Tissue samples are collected through biopsies or surgeries. Fixation: Samples are preserved to prevent degradation, commonly using formalin. Embedding: Tissues are embedded in paraffin wax to maintain structure during sectioning. Sectioning: Thin sections of tissue are cut using a microtome. Staining: Sections are stained to highlight different structures, using dyes like hematoxylin and eosin. Microscopy: Stained sections are examined under a microscope to analyze tissue architecture.
