Trichrome stains are primarily used to identify ๐๐จ๐ฅ๐ฅ๐๐ ๐๐ง (a structural protein), bone or ๐๐ข๐๐ซ๐ข๐ง (the protein that forms blood clots). In general, collagen and bone are highlighted blue-green, while fibrin is highlighted in red.
This image is a case of ๐๐ง๐๐จ๐๐๐ซ๐๐ข๐๐ฅ ๐๐ข๐๐ซ๐จ๐ฌ๐ข๐ฌ in the heart of a cat. In this condition, the ๐๐ง๐๐จ๐๐๐ซ๐๐ข๐ฎ๐ฆ (inner lining of the heart) becomes severely thickened with scar tissue. Scar tissue is primarily made up of collagen, which is why this heart is lined with bright blue on a trichrome stain!
