Effects of luseogliflozin on the mitochondrial morphology and NKX6.1 expression in the pancreatic beta-cells of 10-week-old db/db mice. (A) Images of pancreatic beta-cells from the control and luseo groups stained with Tom 20 (mitochondria, red), insulin (green), glucagon (white), and DAPI (nucleus, blue). Scale bars: 50 µm. (B) Mitochondrial area in the pancreatic beta-cells (n = 5). (C) Electron microscopic analysis of pancreatic beta-cells. Red arrowhead: swelling of mitochondria, red arrows: normal mitochondria. Scale bars: 2 µm. (D) Images of pancreatic beta-cells from the control and luseo groups, stained for NKX6.1 (red) and insulin (green). Scale bars: 50 µm. (E) Ratio of the number of NKX6.1 and insulin double-positive (co-staining) cells to the total number of insulin positive (beta) cells (%) (n = 5). Values are mean ± SD. P values were determined using Student’s t test. **P < 0.01.
