Table 1. Summary of quantitative immunoelectron microscopy data.

Group	FP number per μm	Gold particle per μm2
Control	8.5±0.6	30.3±4.3
Diabetes	0.3±0.2***	2.5±0.8***
Wortmannin	6.9±0.5	19.7±3.9

Abbreviation: FP, foot process.

The quantitation of foot process formation (foot process number per μm) and the gold labeling intensity of glucocorticoid-induced transcript 1 (GLCCI1; gold particle per μm²) are shown.

***P<0.001, control and wortmannin-treated diabetic groups versus the diabetes group by analysis of variance (ANOVA; means±s.e.m., n=3).
