Supervised hierarchical cluster analysis. Significantly regulated genes (p < 0.01) were used for 2D hierarchical clustering of Control, stimulated with PMA/IO (Inflamed), iLP, iLP(A⁻) and iBL23 samples from 3 different patients ((1)RSL-6, (2) RSL-21 and (3) RSL-10)). Each row displays expression of an individual probe set and each column of a biological replicate. The red color represents an expression level above the mean expression of a gene across all samples, and the blue color represents an expression level lower than the mean. The brighter the color, the stronger the factor of gene regulation. White indicates no changes
