Fig. 5From: COPD monocytes demonstrate impaired migratory abilityMigration of CD14+ monocytes towards sputum supernatant. The figure shows a the migration of CD14+ monocytes towards COPD and HNS sputum supernatant and b the migration of CD14+ monocytes isolated from COPD, S and HNS towards COPD sputum supernatant. The data is displayed as mean (SD). The statistical significance of differences observed were determined by a Unpaired t test and b ANOVA with application of Tukey’s multiple comparisons test. Sputum supernatant used in chemotaxis experiments was pooled from n = 3 donorsBack to article page
