What Histological Techniques are Used to Study Lung Tissue?

Several techniques are used in histology to study lung tissue:

- Hematoxylin and Eosin (H&E) Staining: Commonly used to visualize general tissue structure.
- Immunohistochemistry: Uses antibodies to detect specific proteins in lung tissue, helpful in identifying cell types and pathological changes.
- Electron Microscopy: Provides detailed images of lung tissue at the ultrastructural level, useful for studying cell organelles and the surfactant layer.
- Special Stains: Such as Periodic Acid-Schiff (PAS) for mucus and elastin stains to visualize elastic fibers.
