Figure 2: Stem cell markers comparison between FBS and PL cultures of DPSCs. (a) Immunophenotype for expressed MSC surface markers by flow cytometric analysis. The number specifies the percentage of gated cells positive for the indicated protein. Data representative of two experiments. (b) Relative levels of transcripts (fold change) for stemness markers derived from real-time PCR analysis. Statistical significance determined by 2-way ANOVA (; ; ; ), mean + SD, .
