A-C. Epidermal thickness of the back skin was analyzed at the indicated time points in c-JunΔ/Δ Mx1-Cre (A), c-JunΔ/Δ CD11c-Cre (B) and c-JunΔ/Δ K5-Cre-ERT2 mice (C) on Hematoxylin and eosin (H&E) stained sections. (n = 5-21 (A), n = 6-29 (B), n = 5-18 (C); ≥ 2 independent experiments) Data information: Data are shown as mean ± SEM. P‐values were calculated by one-way ANOVA with Tukey (A- C, 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.
