The expression of rBMMSCs changes during osteogenesis. The dynamic expression levels of the osteogenic markers ALP (A), RUNX2 (B), circRNA_1809 (C) and miR-370-3p (D) in rBMMSCs were assessed via fluorescence quantitative PCR at 3 days, 7 days and 14 days after osteogenic differentiation. (E) The expression of circRNA_1809 in rBMMSCs after knocking down circRNA_1809. (F) The expression of miR-370-3p in rBMMSCs after miR-370-3p inhibitor/mimic treatment. The statistical results are expressed as the mean ± SEM, *p < 0.05, **p < 0.01.
