Phenotypic characteristics of mature IL-15 DCs. Immunophenotypic expression of CD40, CD70, CD80, CD83, CD86 and CD209 (DC-SIGN) by (a) short-term cultured IL-15 DCs, (b) long-term cultured IL-15 DCs and (c) conventional IL-4 DCs after maturation induction with either a classic maturation cocktail (cc-mDC; dashed-line histograms) or a TLR7/8 ligand-containing mixture (TLR-mDC; bold-line histograms). Isotype controls are represented by the grey-filled histograms. A detailed overview of the flow cytometry data of mature DCs is provided in "Additional file 1" (n = 4).
