Immunohistochemical localization of smooth muscle myosin in normal human tissuesJA Longtine, GS Pinkus, K Fujiwara and JM Corson
Immunohistochemical localization of smooth muscle myosin, an immunologically distinct contractile protein, was achieved using rabbit anti-human uterine smooth muscle myosin antibodies. In immunodiffusion studies and in cryostat sections, these antibodies were highly specific and reacted with smooth muscle myosin but not with platelet, skeletal muscle, or cardiac muscle myosin. To evaluate comprehensively the structural profile of smooth muscle elements in normal human tissues, an indirect immunoperoxidase technique (peroxidase-antiperoxidase) was applied to a wide variety of specimens. Parallel studies comparing cryostat sections with fixed (10% formalin, B5, Bouin's, or Zenker's solution) paraffin-embedded tissues revealed optimal immunoreactivity, sensitivity, and specificity of staining for smooth muscle myosin using frozen tissues. Strong immunoreactivity was present in muscular tissues such as blood vessels and the muscularis of gastrointestinal and genitourinary tracts. Distinct delineation of smooth muscle elements, including individual smooth muscle cells, and their specific patterns of alignment and organization, were observed, e.g., cells comprising the muscularis mucosae and extending into the lamina propria of the gastrointestinal tract, and myoepithelial cells of skin, exocrine glands, and breast. This method provides excellent morphologic preservation and readily permits unambiguous identification of individual cells containing smooth muscle myosin.
