Figure 5. Pancreatic islet insulin (A) and glucagon (B) staining by diameter (small islets < 50 µm). Small islets had significantly more insulin and glucagon staining than larger islets. (*) indicates a significant difference (P < 0.05). Data are expressed as means ± SE for each animal group. (C: non-T1DM sedentary; CE; non-T1DM exercised; D: T1DM sedentary; DE: T1DM exercised)
