Expression of adhesion-related antigens on CD34⁺ cells. ABM mononuclear cells and G-CSF–MPB were processed and stained with rho123 as described in Materials and Methods. Staining profiles of CD34⁺ gated cells with rho123 versus control isotype, HCA, Thy-1, CD6, and CD49d are shown. The percentage of cells in each quadrant of the plot is indicated.
