Microarray and quantitative polymerase chain reaction (Q-PCR) assays shown that miR-199a had been upregulated during OD of BMSCs, while DEX treatment caused a substantial lowering of miR-199a. Alkaline phosphatase (ALP) activity, Alizarin red (AR) staining, and Q-PCR were used to assess the role of miRNA-199a overexpression in DEX-triggered OD…[Read more]
