Figure 1 SuperArray gene analysis of (A) CCR7 and (B) CXCR4 gene expression in upper and lower lobe surgical lung biopsies from UIP (n  =  7), NSIP (n  =  6), RBILD (n  =  6), and normal margin (n  =  5) tumour patient groups. The data shown are mean (SEM). No significant differences were detected. CCR7, CC chemokine receptor 7; CXCR4, CX chemokine receptor 4; GAPDH, glyceraldehyde 3‐phosphate dehydrogenase; NSIP, non‐specific interstitial pneumonia; RBILD, respiratory bronchiolitis/interstitial lung disease; UIP, usual interstitial pneumonia.
