Figure 3

COPD spotmaps did not show a GM-CSF or TNFα-induced protein profile in a principal component analysis. Data of spot ID 218, 318, 479, 674, 1012, 1332 and 1695 (differentially regulated in COPD patients) from the COPD patient and in vitro stimulation BVA were imported into the EDA software. Principal component analysis (PCA) was performed on 5 non-stimulated (NS) (green), 5 TNFα-stimulated (red), 5 GM-CSF-stimulated (blue), 5 TNFα+GM-CSF-stimulated neutrophil spotmaps (purple), 6 healthy controls (light blue) and 13 COPD neutrophil spotmaps (orange).
