Exercise Increases Insulin Content and Basal Secretion in Pancreatic Islets in Type 1 Diabetic Mice
Figure 3
Islet density and size. (a) Four islets are shown in this 10x field of pancreatic tissue from a healthy control animal. (Green: insulin-positive β-cells; red: glucagon-positive α-cells; blue: somatostatin-positive δ-cells.) (Scale bar: 200 μm.) (b) The islet density was determined as the islet numbers normalized per the area of pancreatic section. Exercise did not increase the number of islets per area in the diabetic groups. (c) Exercise did not increase the islet’s diameter in the diabetic groups. *Indicates significant differences () between control and the two diabetic groups.
