The comparisons of surface markers of DP-MSSCs from normal donors and osteopetrosis patients using flow cytometry. Representative histograms showing the expression of MSC surface markers (CD90, CD44, CD73, and CD105) as analyzed by flow cytometry. The graph shows a comparison of MSC markers (average mean ± 95% confidence intervals) of 15 clones of DP-MSCs extracted from different human exfoliated deciduous teeth. Seven clones from osteopetrosis patients (black bars) and eight clones from normal donors (white bars) were analyzed by flow cytometry. Means and percentages are given, and error bars are 95% confidence intervals. In the green histograms (isotype), samples from both normal and patients were negative for hematopoietic markers (CD14, CD34, CD45, MHC-II, or CD133) (blue histograms). The blue histograms show positive markers in isolates from normal donors (8) and osteopetrosis patients (7), and negative blood markers are represented by orange and pink histograms as isotope controls. * indicates no statistical significance (p > 0.05).
