Pre- and post-expansion PBMCs were analyzed using flow cytometry PBMC were co-cultured with stimulating cells and harvested after 21-day of ex vivo expansion, all pellets were stained with CD56-PE and CD3-FITC mAbs and analyzed by flow cytometry. The percentage of NK cells (CD56+CD3−) in the PBMC population was tested. A: Pre-expansion PBMCs were analyzed by flow cytometry. The percentage of NK cells (CD56+CD3−) in the PBMCs was 9.30 %; B: Post-expansion PBMCs were analyzed by flow cytometry. The percentage of NK cells in the PBMCs was 92.80 %
