useful because of its capacity to stain elastic fibers, the metachromatic granules of mast cells, and differentiates smooth muscle from collagen.

Masson stain: "We reviewed the autopsy files of the New York Harbor Healthcare System and retrieved 25 cases of early acute myocardial infarction. Three autopsy hearts of non-cardiac related deaths were used as controls. Sections from grossly suspected early acute myocardial infaction areas were stained by a Masson’s trichrome stain technique and with desmin by a standard immnunohistochemical method.The ischemic zone surrounding myocardial infarction and the acute infarct itself in 23/25(92%) were detected by desmin depletion, and in all cases with Masson’s trichrome color changes. No change in staining for desmin or Masson’s trichrome were seen in the three controls."

color: Most recipes produce red keratin and muscle fibers, blue or green elastic fiber, collagen and bone, light red or pink cytoplasm, and dark brown to black cell nuclei.
