| Sumario: | The present study describes the changes in the endocrine pancreas of severely diabetic calmodulin-transgenic mice using light microscopic immunocyto-chemical and morphometric techniques. A marked reduction in the number and volume of islets, together with distortion of their normal architecture, was found in diabetic mice. In addition, the volume density of both endocrine tissue and B-cells was decreased. An irregular distribution of non-B-cells was also observed in diabetic animals. The volume density and the percentage of A-cells appeared increased. However, when quantified per area unit, the number of all the islet cell types diminished, although only the decrease in B-cell number was statistically significant. The decrease in B-cell mass might account for the diabetic state developed in this animal model. |
