Figure 3From: Restoration versus reconstruction: cellular mechanisms of skin, nerve and muscle regeneration compared Macrophages infiltrate necrotic muscle fibers. Serial section of murine skeletal muscle in an area of necrosis; corresponding fibers are highlighted by matching color arrows. Evans Blue Dye (EBD) highlights muscle fibers whose plasma membrane is leaking owing to damage; hematoxylin and eosin staining (H&E), showing cellular infiltration in EBD + fibers; histochemistry for esterase staining highlights esterase-enriched macrophages; immunofluorescence analysis for activated macrophages expressing F4/80 (green) confirms the invasion of the muscle fibers by macropohages: laminin (red) and nuclei (blue) are also shown.Back to article page
