Phenotype of cells collected after immature dendritic cell preparation procedure in cancer patients. Peripheral blood mononuclear cells from healthy donors (n = 11) or patients with colorectal cancer (n = 7), renal cell carcinoma (n = 10), or breast cancer (n = 15) were depleted of lymphocytes (2-hour adherence step) and cultured for 7 days in the presence of granulocyte–macrophage colony-stimulating factor and IL-4. Data are expressed as the percentage of cells (with standard error) expressing the HLA-DR⁺Lin^- and HLA-DR^-Lin^- phenotype. *P < 0.01 versus healthy donors.
