Phenotypic profile of BMDCs generated from MM patients versus normal donors. BMDCs were generated by culture of BMMCs from MM patients and normal donors in the presence of GM-CSF and IL-4 for 12 to 14 days. Phenotype was determined using indirect immunofluorescence flow cytometry with MoAbs specific for CD14, CD40, CD80, CD86, and HLA-DR developed with goat anti-mouse FITC antibody for MM BMDCs (A) and normal donor BMDCs (B).
