Expression of surface molecules on BM-derived CD11b⁺GR-1⁺ IMC subsets.

<p>Flow cytometry analysis of cell surface marker expression on lineage (−) CD11b⁺GR-1^hi and CD11b⁺GR-1^low/int IMC subsets was performed as described in the Methods section. Histograms represent expression of the indicated markers on viable CD11b⁺GR-1⁺ cells (open dashed histograms) compared with gated isotype control (filed gray histograms). Data represent of average of frequencies (± SD) from replicate samples. B) Logarithmic mean fluorescence index (MFI) of three experiments for both subsets of CD11b⁺GR-1^hi and CD11b⁺GR^−/low/int IMCs respectively (B & C) ordered by marker from the greatest to the least mean MFI.
