a Immunostaining images showed the upregulated expression of RUNX2 in the CSCM-M group after 3 and 7 days of cell culture (Scale bars: 50 µm). b Rt-qPCR analysis of upregulation of canonical osteogenic markers (Runx2, Smad1, Sp7, Colα1) in the CSCM-M group. n = 3 biologically independent samples; mean ± SEM.*P < 0.05, one-way ANOVA. c Western blot analysis revealed the upregulation of canonical osteogenic markers (BMP2, RUNX2, OPN) in the CSCM-M group. d The timeline of magnetic field loading for the in vivo experiment. Created with BioRender.com. e Micro-CT images, bone volume statistics, and H&E staining of tissue sections f of bone defect repair after 4 and 8 weeks after CSCM and CCM implantation within skull defect in rats. NB new bone. n = 3 rats for per group and per time point; mean ± SEM. *P < 0.05, one-way ANOVA. Source data are provided as a Source Data file. At least three times of experiments were repeated independently.
