Figure 2. The effect of curcumin on miRNA expression patterns in hADSCs. (A) Microarray analysis was performed to analyse the miRNA expression pattern in hADSCs. (B) miRNAs with at least a 2.5-fold increase or decrease in response to curcumin treatment are shown. (C) qRT-PCR detected the expression levels of miR-126a-3p in curcumin-treated hADSCs. (D) qRT-PCR detected the expression profile of miR-126a-3p during osteogenic differentiation of hADSCs. Quantitative data are presented as the mean ± S.D. (n =3). *P<0.05; **P<0.01; ***P<0.001.
