Data shown are means ± s.d. of the mean fluorescence intensity (MFI) of n = 2 for integrins α4 and β1, ICAM-2 and 3; VCAM-1, CD43, Selectins, PSGL-1; n = 5 for integrins β1, α2 and α3, ICAM-1, CD147 and CD98. n = 4 for the remaining molecules. For optimal statistical analysis cytometer detectors were set to include autofluorescence basal signal into the first log of the scale. * p<0.005 **p<0.001, ANOVA Newman-Keuls Multiple Comparison Test.
