Fig. 3. Application of hypoxia to MSCs stimulates their proliferating potential and the potential of multi-lineage differentiation. (A) Multi-passaged MSCs were cultured in normoxic or hypoxic condition, labeled with antibodies against specific surface antigens, CD44, CD73, CD90, and CD105 for MSC positive markers and CD31, CD34, and CD45 for MSC negative markers, and analyzed by counting 10,000 cells at passages 4, 7, and 9, respectively. The surface antigen phenotype was characterized by FACS. Immunoglobulin isotype was used as a negative control for FACS analysis. Negative indicates the labelling of cells with CD34, CD45, and CD11b antibodies. Red-colored histograms illustrate the control immunoglobulin, and blue-colored histograms represent the staining against each specified antibodies as indicated. (B) The graph shows the positive percentages of each MSC marker expression. (C) The graph shows the potency of adipogenic differentiation rate at indicated passages. Data (meanĀ±SEM) are representative of 3 independent experiments.
