Vascular endothelial growth factor B improves impaired glucose tolerance through insulin-mediated inhibition of glucagon secretion

Figure 4 The quantitative analysis of vascular endothelial growth factor B affects the cellular structure of islets. A: The number of islets; B: The relative area of the islet; C: Diameter of the islet; D: Mass of the islet; E: The number of granules in β cells; F: The number of mature granules in β cells; G: The number of immature granules in β cells; H: The number of granules in α cells; I: Mean fluorescence intensity of β cells; J: Mean fluorescence intensity of α cells; K: Mass of the β cells; L: Mass of the α cells. ^aP < 0.05 vs standard diet; ^bP < 0.05 vs high-fat diet-WT; ^cP < 0.05 vs Con. HFD: High-fat diet; AAV: Adeno-associated virus; SD: Standard diet.
