Low-intensity pulsed ultrasound reduces alveolar bone resorption during orthodontic treatment via Lamin A/C-Yes-associated protein axis in stem cells

Figure 3 Low-intensity pulsed ultrasound promotes the osteogenesis of bone marrow mesenchymal stem cells. A and B: Representative alkaline phosphatase (ALP) staining images and statistical analysis; C and D: Representative alizarin red staining images and quantitative data from the alirazin red assay; E: mRNA expression of ALP, type 1 collagen (COL1), runt-related transcription factor 2, and osteocalcin (OCN) folded to control group by quantitative reverse transcription-polymerase chain reaction; F: COL1, ALP, and OCN protein expression in rat alveolar bone tissues analyzed via Western blotting (left), and the band intensities measured via ImageJ software (right). ^aP < 0.05 vs control group, ^bP < 0.01 vs control group. ALP: Alkaline phosphatase; RUNX2: Runt-related transcription factor 2; COL1: Type 1 collagen; OCN: Osteocalcin; LIPUS: Low-intensity pulsed ultrasound; ARS: Alizarin red staining.
