In the present study, we aimed to investigate the function and potential molecular mechanisms of Piezo1 in the odontogenic differentiation of DPSCs.</div></div><div><h3>Methods</h3><div>Piezo1 expression in human dental pulp and DPSCs was detected by immunofluorescence or immunohistochemistry (IHC). The mechanotransduction of Piezo1 ion channels in DPSCs was determined by fluid shear stress (FSS) detection of calcium fluorescence intensity and whole-cell patch clamp detection.
