Impaired muscle regeneration in Stra13−/− mice. (A) Skeletal muscle regeneration was induced by freeze injury in WT and Stra13−/− mice, and muscle was collected on days 2 (D2), 5, 10, and 16 after injury. A clear boundary between the injured and uninjured tissue is visible. At days 10 and 16 after injury, myonecrosis and mononuclear cells are apparent in Stra13−/− muscle. (B) Masson's trichrome staining revealed collagen deposition (blue staining) in Stra13−/− (−/−) muscle at day 16 after injury. Bars, 100 μm.
