Masson's Trichrome Stain
Masson's Trichrome stain is a laboratory technique used to distinguish different tissue components in microscopy. It specifically colors collagen fibers (like those in scar tissue or connective tissue) blue or green, muscle fibers red, and cell nuclei black. This helps pathologists and researchers easily identify and analyze tissue structure, noting areas of fibrosis, inflammation, or abnormal growth. The stain provides a clear contrast between different tissue types, making it a valuable tool in diagnosing diseases and studying tissue organization in health and illness.
