Phenotype and function of FC/4TOO fusion cells.
(A) DCs, 4TOO plasmacytoma, and FC/4TOO fusion cells were analyzed by bidimensional flow cytometry for PKH-26 fluorescence and expression of the indicated antigens. (B) DCs, 4TOO cells, and FC/4TOO fusion cells were analyzed by bidimensional flow cytometry for the expression of MHC class II and Syndecan. (C) DCs (●), 4TOO plasmacytoma (○), FC/4TOO fusion cells (▴), and medium alone (□) were cocultured with C57BL/6 T cells at different ratios for 5 days. [3H]-thymidine uptake was measured at 12 hours after a pulse of 0.037 MBq (1 μCi)/well. The stimulation index is expressed as the mean ± SE of 3 experiments each performed in triplicate.
