Fig 1. Histopathology of adult monkeys with type 2 diabetes mellitus.

Fig 1

(A) Hematoxylin-eosin (HE)-stained section of the pancreas from a 17-year-old cynomolgus monkey with type 2 diabetes mellitus (DM) (S1 Table, Number 1). Most of the islets were replaced by abundant amyloid deposits. (B) HE-stained section of the pancreas from an 18-year-old cynomolgus monkey with DM (S1 Table, Number 3). Most of the islets were replaced with severe amyloid deposits. (C) HE-stained section of the pancreas from a 19-year-old cynomolgus monkey with DM (S1 Table, Number 7) showing hyalinized islets. Very few islet cells remain. (D) Direct fast scarlet-stained section of pancreas from an 18-year-old cynomolgus monkey with DM (S1 Table, Number 5). Hyalinized islets with severe amyloid deposition were positive for direct fast scarlet staining. (E) HE-stained section of the liver from an 18-year-old cynomolgus monkey with DM (S1 Table, Number 3). Marked fatty degeneration was observed in the liver. (F) HE-stained section of the aorta from an 18-year-old cynomolgus monkey with DM (S1 Table, Number 5). Mild atheromatosis with foam cells and sterol clefts was observed in the aorta. Scale bars for a-f, 100 μm.
