Activation of NK and γδ T cells in PBMC cultures stimulated with tumor cell line XG‐7. PBMC (10 × 106 cells) from NPC patients, survivors and donors were stimulated with XG‐7 and cultured for 10 days. The numbers of NK cells (a) and γδ T cells (b) were determined every 2 days by FACS using PE‐labeled CD3 mAb and FITC‐labeled mAbs specific to TCR‐γδ and CD56.
