Figure 3. Inhibition of miR-181a-5p suppressed osteogenic differentiation. (A) miR-181a-5p expression in the scramble and inhibitor groups treated with saline or osteogenesis induction medium. (B, C) ALP and ARS staining of the scramble and inhibitor groups treated with saline or osteogenesis induction medium. (D, E) Transcriptional levels of ALP and RUNX2 by polymerase chain reaction (PCR). (F, G) ALP, RUNX2 and beta-tubulin are determined and quantified by densitometric evaluation of western blots, further normalized to beta-tubulin. All data represent mean ± s.e.m. (n = 6). *P<0.05 compared with the scramble group treated with saline. #P<0.05 compared with the scramble group induced for differentiation.
