Immunofluorescence staining of insulin in the pancreas. Representative histological sections of pancreatic islets of (a) WT, (b) untreated db/db mice, (c) db/db mice treated with rosiglitazone (10 mg/kg/day), and (d) db/db mice treated with AP (300 mg/kg/day) incubated with anti-insulin antibodies. (B) Quantitative analysis of insulin-positive area. Data expressed as mean ± SE (𝑛=5); ^∗∗𝑃<0.01 versus WT; ^##𝑃<0.01 versus db/db control. Original magnification:1000x.
