Killing of K562 <i>in vivo</i> by NK cells from CBCD34⁺ and PBCD34⁺ cultures.

<p>NSG mice were injected with GFP-K562 cells followed by CBCD34⁺-NK cells or PBCD34⁺-NK cells 24 h later. (<b>A</b>) Percentage of GFP-K562 cells detected in the BM, liver, lungs and spleen of NSG mice. (<b>B</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. * <i>P</i><0.05.
