Figure Lengend Snippet: Figure 2. FN-null MEF adhesion to S1-RBD is mediated by αvβ3 integrins and RGD. FN-null MEFs (5 × 105 cells/ml) were preincubated for 30 min with 50 μg/ml integrin-blocking antibodies (A–C) or 25 μM peptide (D–E) before seeding (9.4 × 104 cells/cm2) onto plates precoated with 250 nM S1-RBD (A and D), FNIII10 (B and E), or type I collagen (C). Relative cell number was determined by crystal violet staining. Data are mean ± SEM, normalized to corresponding vehicle (PBS) controls; n = 3 independent experiments performed in triplicate. One-way ANOVA, Bonferroni’s post hoc test: A–C *p < 0.05 versus PBS, IgG; +p < 0.05 versus PBS, IgM; #p < 0.05 versus PBS, anti-α5+β1; D–E *p < 0.05 versus PBS; #p < 0.05 versus corresponding negative control, RAD or KGD.
