Cell cycle status of blood and lymphoid organ DCs. Blood PBMCs were enriched for DCs and stained for HLA-DR, CD11c, CD16, CD14, BDCA1, and BDCA3. Axillary LN or tonsil cells were enriched for DCs and stained for HLA-DR, CD11c, CD14, BDCA1, and BDCA3. Cells were fixed, permeabilized, and stained for Ki67 and DAPI. BDCA1+ DCs were gated as HLA-DR+CD11c+CD16−CD14−BDCA1+, Clec9A+ DCs were gated as HLA-DR+CD11c+CD16−CD14−BDCA3+, and pDCs were gated as HLA-DR+CD11c−. (A) Representative results for BDCA1+ DCs and pDCs are shown. (B) The percentage of Ki67+DAPIhigh cells is shown in six independent experiments for blood DCs and nine independent experiments for lymphoid organ DCs (three LNs and six tonsils). Horizontal bars indicate the mean. ***, P < 0.0001.
