Figure 2. The effect of diabetes on VCAM-1 expression is dependent on retinal vessel size.

Summarized data from confocal immunofluorescence microscopy experiments showing mean fluorescence intensity of VCAM-1 in retinal vessels divided into quartiles depending on vessel diameter (<10 µm, 10–15 µm, 16–23 µm and >23 µm). Each graph represents the expression-diameter relationship in the different genotypes. White bars are for control and grey bars for diabetes. The two first bars in each graph (in white and black, for control and diabetes respectively) show the same data as in Figure 1 , but are displayed here as references. *p<0.05 and ***p<0.001 indicate differences between control and diabetes of the same size and genotype.
