Enumeration of adhesion to fibronectin of blood HPC from COPD and normal subjects to (a) SDF-1α, (b) HGF, and (c) VEGF. (d) Comparison of the optimal adhesive response to SDF-1α (10 ng/mL), HGF, and VEGF (both 50 ng/mL) shows no significant difference between the two groups of subjects. Data are presented as mean ± SEM (); within group comparisons to diluent control.
