GD-MSCs characterization.

<p>(A) Histograms represents CFU-F quantification per 10⁵ mononuclear cells (left panel) and mean cell number per CFU-F (right panel) obtained after culture of control (Ct) or GD BM samples (n = 10 and 7 for GD patients and controls respectively). (B) MSCs growth kinetics: cumulative population doubling (CPD) are shown for Ct and GD-MSCs (n = 5 and 10 respectively). (C) Cell cycle analysis was performed by flow cytometry on Ct and GD-MSCs. The percentage of cells in each phase of the cell cycle was determined by gating G0/G1, S and G2/M cells (n = 8 and 6 respectively). (D) Representative FSC/SSC flow cytometry profile of Ct and GD-MSCs. (E) Ct and GD-MSCs were stained with anti-alpha-tubulin (red) and with Hoechst for nuclear staining (blue). Typical non-round nuclei (angled panels) and large nuclei (arrows) were observed in GD-MSCs. Scale bars represent 50 µm. A and C: * indicates <i>P</i><0.05.
