Location of monocytes and DCs. (A) The distribution of CD56 among lineage (CD3/14/19/20)–negative cells; (B) gating strategy used to identify CD14⁺ monocytes, CD16⁺ monocytes/DC, CD123⁺ plasmacytoid DCs (PDCs), and CD11c myeloid DCs, and comparison of CD56 expression above isotype; (C) expression of CD56 and CD7 by defined populations; (D) comparison of HLA-DR versus lineage plots with antibodies to CD56, CD7 or both, in lineage.
