Fig. 3From: Islet Amyloid Development in a Mouse Strain Lacking Endogenous Islet Amyloid Polypeptide (IAPP) but Expressing Human IAPP(A) A pancreatic islet of a hIAPP+/+ mIAPP−/− male mouse, fed a high-fat diet for 9 months. Many scattered amyloid deposits are seen within the islet (yellow-red). Congo red in polarized light, examined with partially crossed polars. 200 × magnification. (B) Detail of a pancreatic islet of the same animal as in (A). Small extracellular amyloid deposits are evident. In addition, a cell, obviously filled with amyloid is seen. Congo red in polarized light, examined with partially crossed polars. 1000 × magnification.Back to article page
