Gene expression levels of ALI-PBEC from four donors after 15 days of air-exposed culturing. a 2D hierarchical clustering of 190 genes with donor-dependent expression levels (BH q value ≤0.05). b 2D hierarchical clustering of the 47 genes that are differentially expressed with a FC ≥ 2 between any of the four donors. Tiles represent the median expression levels of six independent measurements for each donor. Genes with a FC ≥ 5 between any of the four donors are marked in red (color figure online)
