Total numbers of pancreatic apoptotic cells present in control and nonobese diabetic (NOD) strains during the early postnatal period, as determined by the terminal transferase-mediated dUTP nick-end labeling assay. The numbers of positive cells were counted by two individuals and expressed per square millimeter of total pancreatic surface area. Mean values ± sem (n = 10 mice per strain/age group).
