miR-128 affects osteogenic differentiation of rBMSCs by functionally targeting DKK2
(A) Transfection efficiencies of Lenti-DKK2 tested at 48 and 72 h after transfection using qRT-PCR and Western blot analysis, respectively. (B) mRNA expression of osteogenic factors as assessed after treatment with Lenti-DKK2 and miR-128 mimic. (C) Western blot analysis. (D) ALP activity. (E) ARS staining; **P <0.01, *P <0.05, NS, not significant.
