What is the purpose of Gomori's reticulin method and which tissues are suitable as controls?

Gomori's reticulin method stains reticular fibers, which are networks of type III collagen, in tissue. The silver technique makes these delicate fibers appear as a dark, black reticular framework, outlining the supportive stroma of organs. Because many organs rely on a dense reticular network for structure—especially liver, spleen, and lymph nodes—these tissues are ideal controls. They routinely show a prominent reticulin framework around portal tracts and sinusoids in the liver, the splenic cords and trabeculae in the spleen, and the reticular skeleton supporting white pulp in lymph nodes. Using them as controls helps verify that the stain is working properly and provides a reference pattern against which pathological changes can be recognized. Other stains target different components—elastin in arteries, or basement membranes with different methods—so they wouldn’t be appropriate controls for a reticulin-specific stain.
