qRT-PCR detection of Ccl2 mRNA in CD11c+MHCII+ cells sorted from IMQ-treated back skin (8h). (n = 5-12; 3 experiments). Data information: Data are shown as mean ± SEM. P‐values were calculated by multiple t-test with Tukey multiple comparison test. Statistical significance: ns > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001, **** P < 0.0001. See Appendix Table S3 for exact P‐values.
