Figure 6. Killing of K562 in vivo by NK cells from CBCD34⁺ and PBCD34⁺ cultures.

NSG mice were injected with GFP-K562 cells followed by CBCD34⁺-NK cells or PBCD34⁺-NK cells 24 h later. (A) Percentage of GFP-K562 cells detected in the BM, liver, lungs and spleen of NSG mice. (B) Percentage of NK cells detected in the BM, liver, lungs and spleen of NSG mice. The statistical analysis was performed using Mann-Whitney test. * P<0.05.
