Different staining techniques are used to visualize specific tissue components. The most common is the Hematoxylin and Eosin (H&E) stain, which differentiates between the nucleus (stained blue) and the cytoplasm (stained pink). Other stains, such as Masson's Trichrome and Periodic Acid-Schiff (PAS), are used to detect collagen and carbohydrates, respectively.
