(A) Tumor formation by SW1-C-CD83, SW1-C-1D8, and SW1-C transplanted (106 cells per mouse) to naive mice. (B) Tumor formation by SW1-C (106 cells per mouse) to mice that had been immunized four times with MMC-treated cells (2 × 106 per mouse) from either M2-CD83 or M2-1D8. (C and D) Tumor formation by SW1-P2 cells (106 per mouse) transplanted to mice (C) and survival of mice (D) that had been immunized three times, 7 days apart, with MMC-treated M2-CD83 cells (2 × 106 per mouse) and reimmunized as indicated by arrows. (E and F) Inhibited outgrowth of SW1-C (E) and SW1-P2 (F) in mice immunized twice, 1 week apart, by a mixture of M2-CD83 and M2-1D8 cells (106 of each per mouse). (n = 5 mice per group.)
