Fig. 4From: β-Cell Apoptosis in an Accelerated Model of Autoimmune DiabetesConfocal microscopy of islets from B7-1 NOD.scid mice labeled for insulin (green: A, D) and TUNEL (red; B, E) 10 days after transfer of splenocytes from diabetic NOD mice. The overlaid image (C) reveals insulin-positive β cells undergoing apoptosis. Well-granulated insulin-positive islets were negative for TUNEL (D–F).Back to article page
