Flow cytometric analysis of BM and PB from normal and mobilized animals. Mononuclear cells from BM and PB from control and Ptx-treated mice and one Ptx-treated monkey (bottom 2 panels) were labeled with directly conjugated antibodies. The shaded areas represent isotype controls and solid lines represent cells labeled by the directly conjugated antibodies noted. Numbers within histograms represent percent positive cells (top numbers) and mean fluorescence intensity (MFI; bottom numbers). Bars in anti-CD11a and anti-CD29 histograms represent proportions of cells with high expression.
