Gene expression infograms for time course of bleomycin-induced lung fibrosis. A: gene expression infogram for all 533 differentially expressed genes. B: gene expression infogram for most informative genes that code for extracellular matrix (ECM) components or play a significant role in ECM metabolism. Every row represents a gene and every column a mouse lung sample. Increased genes are shown in progressively brighter shades of yellow, and decreased genes are shown in progressively darker shades of purple. Genes shown in gray are not different between the groups. The baseline per gene was defined as the geometric mean of the expression of the gene in the saline controls mice at the initial time point.
