Mechanical Stress Modulates the RANKL/OPG System of Periodontal Ligament Stem Cells via α7 nAChR in Human Deciduous Teeth: An In Vitro Study
Figure 2
Effects of mechanical pressure on the osteogenic and the osteoclastic differentiation in PDLSCs. (a–c) qRT-PCR was performed to assess RUNX2, ALP, RANKL, and OPG expression levels in different groups. Values are reported as (, , and ; one-way ANOVA). (d) The expression levels of RUNX2, ALP, RANKL, and OPG in PDLSCs from each group were examined via Western blot assays. The cyclic hydraulic pressure was performed with a fixed frequency of 0.1 Hz at different ranges for 2 hours/day for three consecutive days.
