Cell-surface phenotype of cells stained after 7 days of culture with GM-CSF and IL-4. This representative analysis out of five shows no difference between AC, CD34⁻ AC, and NA-AC derived DCs either in lineage (CD4, CD14, CD1a) or in costimulatory antigen (CD40, MHC class II, CD80) expression. Controls (dotted lines) were isotype-matched irrelevant antibodies.
