Flow cytometric analysis of the surface expression of CXCR-1 and CXCR-2 on ASM cells from CF and control patients. Representative examples of the expression of CXCR1 and CXCR2 from CF and control patients are shown in panels 2A, 2B, 2C and 2D respectively. The histogram outlined by the darkest lines represents the distribution of isotype control cells, the lightest shade represents the cells stained with specific antibody and the intermediate shade represents the difference between positively stained cells and isotype controls. Panel E shows the percentage of cells stained for CXCR1 and CXCR2 from 4 different cell preparations of CF and control patients.
