Figure 3. Representative images of pancreatic islet glucagon staining (A) and glucagon quantification (B). Pancreatic islets from both sedentary and exercised rats with T1DM (D and DE) had significantly more glucagon 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)
