miR-708-5p negatively regulates the osteoblast differentiation of BMSCs. (a) Alizarin Red S staining (100× magnification) showing that mir-708-5p inhibited the deposition of osteogenic calcium 14 days after BMSC osteoblast induction. (b) Quantitative analysis of ALP activity in BMSCs. mir-708-5p inhibited the ALP activity of osteoblasts. (c, d) Quantitative PCR and western blot analyses showing the effect of miR-708-5p on the mRNA and protein expression of BMP2, BMP4, and Runx2 in osteoblasts. Data are the means ± SD of three independent experiments. *P < 0.05 and ** P < 0.01 versus control.

OSI, osteogenic induction group; CON, non-osteogenic induction group; BMSCs, bone marrow mesenchymal stem cells; ALP, alkaline phosphatase; BMP, bone morphogenetic protein; Runx2, Runt-related transcription factor 2.
