![Intergins alpha 4/ alpha 9 are responsible for the action of osteopontin (OPN) in the augmentation of macrophage (Mφ) M2 polarization and angiogenic capacity. (A) Relative mean fluorescence intensities (MFIs) of integrins alpha 4/ alpha 9 were measured by FACS analysis in each Mφ subset. Anti-integrin alpha 4 or alpha 9 antibodies (Abs) and each isotype-matched control Ab were used at 10 µg/mL, n = 4 [***p < 0.001 vs. untreated, ###p < 0.001 vs. interleukin (IL)-10 alone]. (B) Representative confocal laser scanning immunofluorescence overlay images of integrin alpha 4 (green) and DAPI (blue), as well as those of integrin alpha 9 (red) and DAPI (blue) in Mφ (–) and Mφ (IL-10 + IL-18). Scale bar represents 20 µm. (C) Relative MFI of CD163 was measured by FACS analysis in each Mφ subset. Anti-integrin alpha 4 or alpha 9 Abs and each isotype-matched control Ab were used at 10 µg/mL, n = 4 (***p < 0.001 vs. untreated, ###p < 0.001 vs. IL-10 alone, †††p < 0.001 vs. IL-10 + IL-18). (D) The total areas and lengths of tube-like structures were determined by the Matrigel tube formation assay where b.End5 was cocultured with each Mφ subset. Anti-integrin alpha 4 or alpha 9 Abs and each isotype-matched control Ab were used at 10 µg/mL, n = 6 (***p < 0.001, **p < 0.01, *p < 0.05 vs. untreated, ###p < 0.001, ##p < 0.01, #p < 0.05 vs. IL-10 alone, †††p < 0.001 vs. IL-10 + IL-18). Integrin alpha 4 = ITGA4; Integrin alpha 9 = ITGA9. All data are expressed as means ± SEM and were analyzed by a one-way ANOVA followed by Tukey’s test.
