Fig. 6From: Extracellular vesicle distribution and localization in skeletal muscle at rest and following disuse atrophyCD81 protein is primarily detected in the interstitial space with some expression near the myonuclei and on myofiber membranes. A Cross-section of the soleus muscle from a control F344/BN rat showing dystrophin and CD81+ cells. The magnified image shows the CD81 protein in the extracellular space (gray arrows), in the mononuclear cells (white arrows), and in the surrounding myonuclei (white arrowheads). B Image of the CD81 expression in the myofiber membrane. C The same image as B, with dystrophin border shown. D Close-up image demonstrating the expression of CD81Back to article page
