Figure 1.

Phenotype of monocyte-derived cell populations. Expression of markers by dendritic cells (DC), antigen-presenting cells (APC) and macrophages (MPh) was assessed by flow cytometry. Lower panels include cell populations activated with lipopolysaccharide (LPS) for 24 h. Debris and dead cells were excluded on the basis of forward scatter and side scatter. Data shown for at least six independent experiments; different epithelial cell donors and blood donors were used in each experiment. Horizontal lines represent median values. *p<0.05 (Wilcoxon test).
