Tissue staining is a critical step in histology that allows for the visualization of different cellular components. Hematoxylin stains cell nuclei blue, while Eosin stains the cytoplasm and extracellular matrix pink. These contrasting colors make it easier to distinguish between different cell types and structures within a tissue. Specialized stains can also be used to identify specific molecules or structures, such as connective tissue fibers or microorganisms.
