Glomerular ultrastructure in nondiabetic mice. A and B: examination of kidneys by transmission electron microscopy (TEM) revealed no qualitative differences in glomerular ultrastructure in nondiabetic COX2+/+ mice or nondiabetic COX2−/−POD mice. C: number of filtration slits per micrometer (µm) of glomerular basement membrane (GBM) was similar in both groups. For the studies, two mice were studied in each group. Statistical analysis was performed using an unpaired t-test.
