Comparison of Osteogenic Differentiation Potential of Human Dental-Derived Stem Cells Isolated from Dental Pulp, Periodontal Ligament, Dental Follicle, and Alveolar Bone

Figure 4

Gene expression for osteogenic differentiation. qRT-PCR was performed to analyze the potency of osteogenic differentiation in DPSCs, PDLSCs, DFPCs, and ABMMSCs at days 0, 7, 14, and 21. The -axis represents the relative mRNA fold change, which was calculated using the 2^−ΔΔCt formula with β-actin as the internal control. Error bars represent the SD () (, , and vs. DPSCs; ^#, ^##, and ^### vs. PDLSCs; ^&, ^&&, and ^&&& vs. DFPCs; ^†, ^††, and ^††† vs. ABMMSCs).
