Time course of expression after saline and at days 2, 5, 7, and 14 after bleomycin, in C57BL/6 mice of selected genes from Clusters A (A–D) and B (E and F) that were also induced by bleomycin in this strain. Each panel shows data for genes that followed a similar temporal pattern of induction. Values for each gene are plotted as a percentage of maximal induction for that gene, which is considered 100%.
