Which stain is specifically used to demonstrate reticulin fibers in tissue sections?

Reticulin fibers form a delicate network of type III collagen that outlines tissue architecture. To visualize this specific framework, Gomori's reticulin stain uses silver impregnation to deposit silver on the reticular fibers, making them appear black against a light background. This targeted visualization is particularly useful for assessing the scaffolding of organs like liver, spleen, and bone marrow, and for detecting architectural changes such as fibrosis or cirrhosis that disrupt the reticular network. The other stains highlight different structures: Verhoeff's stain marks elastic fibers, Masson Trichrome differentiates collagen but isn’t specific to the reticular network, and Periodic acid Schiff stains carbohydrates including basement membranes but does not specifically emphasize reticular fibers.
