Modulating Mesenchymal Stem Cell Behavior Using Human Hair Keratin-Coated Surfaces

Figure 4

Flow cytometry analysis of stem cell marker expression. Human MSCs from Donor A and Donor B were cultured on uncoated or keratin-coated surfaces from passage 4 to passage 7. The stem cell markers STRO-1 (a and b) and CD49a (c and d) were assessed at passage 5 and passage 7. All plots show relative percentage expression levels. Representative scatter plots (FSC, -axis and SSC, -axis) show gating of live cells, while histograms show the distribution of expression of the surface markers; , .
