چکیده انگلیسی
In this study, we sorted total bone marrow (BM) into six distinct subsets based on surface expression of CD31 and Ly6C and investigated the capacity of these subsets to acquire characteristics of plasmacytoid dendritic cells (PDCs) after in vitro culture with FMS-like tyrosine kinase 3 ligand (Flt3-L). Cultured CD31high/Ly6Câ cells were the only subset that consistently developed immunophenotypic, functional, and morphologic characteristics of PDCs. Culture of this subset resulted in expression of CD11c, B220, and the PDC-specific marker 440C and secretion of interferon-α (IFN-α) when stimulated with CPG ODN 2216. Cultured cells displayed the typical plasmacytoid morphology of PDCs with eccentrically located nucleus and mature lymphoid chromatin. Unlike conventional dendritic cells (CDCs) that can be generated from CD31high/Ly6Câ, CD31+/Ly6C+, and CD31â/Ly6Chigh BM subpopulations, PDCs can only be derived from the CD31high/Ly6Câ subset, the subset that reportedly contains the highest frequency of early and late cobblestone area forming cells (CAFC).
