Effect of miglitol on the number of lipid droplets in BAT cells. Histology of BAT was examined by HE staining (Scale bar = 40 μm). A, B and C show the representative histology of normal chow diet mice, high-fat diet mice and miglitol-treated high-fat diet mice, respectively. D: The number of cells/area was counted. Values are means ± SE for 5–6 mice. aP < 0.05, vs mice fed normal chow diet (NC). cP < 0.05, vs mice fed high-fat diet alone (HF).
