Eleven day-old full-thickness excisional wounds stained with the following antibodies: (a–d) neutrophil-specific, RB6-8C5; (f–i) macrophagespecific, F4/80; (k, l) toluidine blue, for mast cells (arrowheads). Scale bar, 100 µm. Mouse TG strains 4 and 5 (low-expressors) and strains 1 and 3 (high-expressors) are illustrated in the panels, while the graphs (e, j, m) show aggregate data for all strains. P values are indicated for significant differences. NS, not significant. Results represent mean ± SEM from at least 9 optical fields each from the low Hoxb13 expressors, high Hoxb13 expressors, and WTLM.
