Immunohistochemical staining for S100A1 in human hearts. A: Massive depletion of H-FABP in ischemic areas was observed (bar: 50 μm). B: Strong cytoplasmic S100A1 immunoreactivity can be seen in normal cardiomyocytes (bar: 50 μm). C: A significant reduction in S100A1 expression in ischemic areas was observed (case 5, bar: 50 μm).
