Overview of H&E Staining
- H&E Staining stands for Hematoxylin and Eosin staining. It is the most widely used stain in medical diagnosis and histology.
- The technique is considered the gold standard for examining tissue samples under a microscope to distinguish between normal and diseased cells.
Components of the Stain
- H (Hematoxylin): This is a basic dye that stains acidic structures, such as the cell nucleus, a deep blue or purple color. Hematoxylin is derived from the logwood tree (Haematoxylon campechianum).
- E (Eosin): This is an acidic dye that stains basic structures, such as the cytoplasm and extracellular matrix, in various shades of pink or red.
Key Diagnostic Utility
- Nuclear Morphology: Because Hematoxylin highlights the nucleus, pathologists use it to observe nuclear size, shape, and chromatin patterns, which are critical in diagnosing cancer.
- Cytoplasmic Detail: Eosin provides contrast, allowing for the visualization of the cytoplasm, muscle fibers, and connective tissue, helping to differentiate tissue types.
- Process: The procedure typically involves dewaxing, hydration, staining with hematoxylin, bluing, counterstaining with eosin, dehydration, clearing, and mounting.
