Resistance of K562DR1+ tumors to adoptively transferred PBMC. Two weeks after SC inoculation of 2 × 107 K562 or K562β or K562DR1 cells followed by intravenous administration of 5 × 107 human PBMC, all tumors were excised, trimmed of surrounding tissue, and weighed (gram). A typical experiment is shown.
