In vitro cytotoxicity levels of HLA-DR13–expressing or HLA-DR13–nonexpressing MNCs.
In vitro cytotoxicity levels of HLA-DR13–expressing (n = 17) or HLA-DR13–nonexpressing (n = 87) MNCs isolated from G-CSF–mobilized donors blood stem cell harvests against K562 tumor target cells (P < .01). ● indicates HLA-DR13 absent; ▵, HLA-DR13 present. *indicates the statistical significance of the value as compared to nonmobilized blood.
