Real-time RT-PCR results.

	COPD patients (N = 12)	Controls (N = 7)	p value
CXCR4	0.05 (0.01–0.31)	0.87 (0.34–1.35)	0.01
SDF1a	0.03 (0.01–0.06)	0.32 (0.18–0.43)	0.002
CCL19	0.001 (0.00–0.03)	0.02 (0.004–0.04)	0.01
CCL21	0.00 (0.00–0.04)	0.04 (0.04–0.19)	0.02
CCR7	No expression	No expression	NS

Values are expressed as median (interquartile range); p value < 0.05 as statistically significant; measurements are 2^−DCT; DCT= Ctgene – Ctgapdh.
