Effect of Wnt2 and Wnt7b regulated by miR-503-3p on osteogenic differentiation of hASCs under cyclic strain (*p < 0.05, there were significant differences between these two groups) a After co-transfecting miR-503-3p mimic with EX-Wnt2 and EX-Wnt7b, real-time PCR showed RUNX2, ALP, SPARC, Wnt2, Wnt7b, and β-catenin were increased, than the miR-503-3p mimic and EX-Ctrl group. b Protein blots were listed in the left column. After co-transfecting miR-503-3p mimic with EX-Wnt2 and EX-Wnt7b, western blot showed that RUNX2, ALP, SPARC, Wnt2, Wnt7b, cytoplasmic, and nuclear β-catenin increased, than the miR-503-3p mimic and EX-Ctrl group. c Both ALP activity and the content of Ca2+ significantly increased when co-transfecting miR-503-3p mimic with EX-Wnt2 and EX-Wnt7b. d After co-transfecting miR-503-3p mimic with EX-Wnt2 and EX-Wnt7b, the immunofluorescence intensity of nucleus β-catenin was enhanced. e After co-transfecting miR-503-3p inhibitor with siWnt2 and siWnt7b, real-time PCR showed that RUNX2, ALP, SPARC, Wnt2, Wnt7b, and β-catenin decreased, than the miR-503-3p inhibitor and siR-Ctrl group. f Protein blots were listed in the left column. After co-transfecting miR-503-3p inhibitor with siWnt2 and siWnt7b, western blot showed RUNX2, ALP, SPARC, Wnt2, Wnt7b, cytoplasmic, and nuclear β-catenin decreased, than the miR-503-3p inhibitor and siR-Ctrl group. g Both ALP activity and the content of Ca2+ significantly decreased when co-transfecting miR-503-3p inhibitor with siWnt2 and siWnt7b. h After co-transfecting miR-503-3p inhibitor with siWnt2 and siWnt7b, the immunofluorescence intensity of nucleus β-catenin was decreased. i After co-transfecting miR-503-3p inhibitor with siβ-catenin, real-time PCR showed that RUNX2, ALP, and SPARC decreased; Wnt2, Wnt7b and β-catenin decreased, than the miR-503-3p inhibitor and siR-Ctrl group. j Protein blots were listed in the left column. After co-transfecting miR-503-3p inhibitor with siβ-catenin, western blot showed that RUNX2, ALP, and SPARC decreased; Wnt2, Wnt7b, cytoplasmic and nuclear β-catenin decreased, than the miR-503-3p inhibitor and siR-Ctrl group. k Both ALP activity and the content of Ca2+ significantly decreased when co-transfecting miR-503-3p inhibitor with siβ-catenin. l After co-transfecting miR-503-3p inhibitor with siβ-catenin into hASCs, the immunofluorescence intensity of nucleus β-catenin was decreased. m After co-transfecting miR-503-3p mimic with EX-β-catenin, real-time PCR showed that RUNX2, ALP, and SPARC increased; Wnt2, Wnt7b, and β-catenin increased, than the miR-503-3p mimic and EX-Ctrl group. n Protein blots were listed in the left column. After co-transfecting miR-503-3p mimic with EX-β-catenin, western blot showed that RUNX2, ALP, and SPARC increased; Wnt2, Wnt7b, cytoplasmic, and nuclear β-catenin increased, than the miR-503-3p mimic and EX-Ctrl group. o Both ALP activity and the content of Ca2+ significantly increased when co-transfecting miR-503-3p mimic with EX-β-catenin. p After co-transfecting miR-503-3p mimic with EX-β-catenin, the immunofluorescence intensity of nucleus β-catenin was increased
