Representative flow cytometric histograms from bone marrow aspirate specimens after HPC mobilization showing a 3-color cytofluorometric analysis of the expression of adhesion molecule antigen on CD34+ cell population. The results were estimated as the mean fluorescence intensity (MFI). The histograms (A) and (B) are IgG1 FITC and PE controls. (C) CD106, (D) CD135, (E) CD184, (F) CD62L, (G) CD49d, (H) CD11a, and (I) CD44 antigen on CD34+ cell population. The gating protocols have been described before.
