Canonical pathways significantly enriched (P < 0.01) in the myofibroblast group contained 88 unique, characterized genes making 167 appearances, with 77 (87%) appearing in three pathways or fewer. The equivalent keratocyte data show 42 genes making 58 appearances, with 41 (98%) appearing in three pathways or fewer. Forty-four genes made 68 appearances and are shown in the “both phenotypes” column, with 40 (91%) appearing in three pathways or fewer. The aggregate data contained 163 unique genes, whereas (88 + 42 + 44) = 172 were expected from the component groups (i.e., there are nine redundancies). Redundancies among groups were due to multiple panels that may assign a given gene to more than one group. The following genes: BIRC5, COL1A1, FAS, IGF1, IGFBP5, MAF, GSR, SOD2, SQSTM1 and RRAS2 were redundant among groups. Each of these genes appears in Tables 3, 4, and 5.
