Proportions of α- and δ-cells in small and big islets. Areas stained for glucagon and somatostatin in the largest cross section of small (<60 µm) and big (>100 µm) islets. The data refer to observations made in paraffin sections of pancreas and isolated islets. All values are given as means ± SEM. ^∗ P < 0.001 compared with small islets stained for glucagon in the pancreas. ^# P < 0.05 compared with small islets stained for somatostatin in the pancreas. ^† P < 0.05 compared with small isolated islets stained for glucagon. ^¤ P < 0.001 compared with small isolated islets stained for somatostatin.
