Figure 2. Representative images of pancreatic islet insulin staining (A) and insulin quantification (B). Pancreatic islets from both sedentary and exercised rats with T1DM (D and DE) had significantly less insulin staining than sedentary and exercised non-T1DM (C and CE) rats (P < 0.05). (*) indicates a significant difference from C. (#) indicates a significant difference from CE (P < 0.05). Data are expressed as means ± SE for each animal group. (x40 magnification; Bar = 50 µm)
