Graft-versus-host disease (GVHD)-free survival. a Mice were injected with either unpurified mononuclear cells (dashed line) or purified NK cells (solid line) from the same donor in each experiment. b Flow cytometric analysis of cells from the spleen of mice with GVHD (right panels) showed a large number of human CD45⁺CD3⁺CD56⁻ T cells with minimal residual murine CD45⁺ leukocytes (in contrast to mice that received purified NK cells, left panel). Results were combined from two independent experiments on 20 mice with NK cells from different donors.
