(A) Characterization of DPSCs at the first passage of culture: cytometric analysis of CD90, CD105, CD45 and CD34 markers in DPSCs. Histograms represent the number of cells (y-axis) and fluorescence intensity (x-axis) relative to unstained control cells (black histogram), and cells marked with specific antibodies against surface proteins (red histogram). (B) Growth curve of DPSCs: the average DT is 49±2 h. (C) Growth performance was studied for up to 21 days.
