H&E staining of the omenta of unencapsulated islet transplant controls. (A) H&E stained section of a typical healthy, untreated rat omentum, shown for comparison (scale = 0.5 mm; magnification = 40 × ). (B) Omentum of rats transplanted with unencapsulated islets, explanted 11 days post-transplant after blood glucose levels, indicated that graft rejection had occurred (scale = 0.5 mm; magnification = 40 × ). (C) Higher magnification of the center image (white square frame) showing significant lymphocyte infiltration in the region (scale = 150 μm; magnification = 200 × ). H&E, hematoxylin and eosin.
