For immunophenotyping of isolated progenitor cells and to monitor evolution upon amplification, flow cytometry was performed with a FACS CaliburTM (Beckton Dickinson, 11, rue Aristide Bergès, ZI des Iles, BP4, 38801 Le Pont de Claix Cedex, France) cytometer. The different phases of the cell cycle were observed after propidium iodide labeling as described [40 (link)], and the flow cytometry histograms were analyzed with the Modfit LT v3.2 software (Verity Software House, Topsham, ME, USA). Cells were labelled with VioBlue-conjugated anti-CD34 antibody, phycoerythrin (PE)-conjugated anti-CD38 antibody, and a lineage mix of fluorescein isothiocyanate (FITC)-conjugated anti-CD3, CD19, CD56, CD13, CD14, and CD11a antibodies (Miltenyi Biotech). For differentiation assay, a complementary labelling was carried out with Brilliant Violet-conjugated anti-CD34 (Beckton Dickinson Pharmingen), FITC-conjugated anti-CD36 (Beckman Coulter, Villepinte, France), PE-conjugated anti-CD235a (GPA) (Beckman Coulter), and allophycocyanin (APC)-conjugated anti-CD71 (Beckman Coulter) antibodies.
