(A–C) Quantitative RT-PCR analyses of Ccl3 (A), Ccl4 (B), and Ccl5 (C) gene expression (n = 6). (D–G) Cell types expressing CCL3 (D, day 1; E, day 6), CCL4 (F, day 6), and CCL5 (G, day 6). Representative results from 6 independent experiments are shown. Signals were merged digitally. Original magnification, ×400. All values represent mean ± SEM. **P < 0.01 versus uninjured skin (time 0).
