Masson’s Trichrome Staining is a histological staining method used for selectively stain collagen, collagen fibers, fibrin, muscles, and erythrocytes. This book discusses recent advances in new anti- and pro-inflammatory pathways in diabetic disease, and identifies new diagnostic immunological methods that offer potential companion diagnostics for diabetic diseases. The cords and clumps of epithelial cells are sharply outlined by the blue collagenous fibers. Masson's Trichrome Stain is a stain that can yield a multicolor result on the tissue. Masson's Trichrome is often used to demonstrate increased collagen deposition that is associated with replacement of functional tissue by scar tissue. Even though it has red counterstains, it is popular for its ability to stain collagen fibers blue.
