Figure 4From: Ex-vivo expanded human NK cells express activating receptors that mediate cytotoxicity of allogeneic and autologous cancer cell lines by direct recognition and antibody directed cellular cytotoxicityDistribution of lineage-specific phenotypic markers on PBMC and separate cell fractions obtained after counter current elutriation. PBMC and elutriated cell fractions were stained with various lineage-specific directly-conjugated antibodies and analyzed by flow cytometry (A). Average number of cells and phenotypic distribution (%) expressing lineage-markers in elutriated cell fractions (n = 11) (B).Back to article page
