pDCs are critical for the maintenance of skin fibrosis and for the presence of CXCL4 in the skin. Fibrosis was induced by injection of BLM in WT mice for either 3 or 5 weeks (wks) or in CLEC4C-DTR mice for 5 weeks as described in Materials and Methods. At 3 weeks of BLM treatment, pDC depletion was achieved in CLEC4C-DTR mice by DT injection (in red) while fibrosis induction was sustained for 2 more weeks. (A) Average of skin thickness and (B) of the number of Siglec-H+ cells in the skin. (C) Representative images of the cxcl4 transcript by RNA in situ hybridization (brown signal; original magnification, ×400; inset, ×630) and (D) average of the number of CXCL4+ cells. Experiment was performed twice (n = 4 to 10 per group). All results are represented as means ± SEM, and statistical significance was evaluated using a Mann-Whitney U test. *P < 0.05, **P < 0.01, ***P <
