Effect of miR-128 and miR-216a on the differentiation of HUMSCs (a) Real-time PCR analysis of miR-128 or miR-216a expression level after transfection with miRNA mimic or inhibitor; The miRNA expression level in the control group was set as 1, *P＜0.05 vs the control group; Isl1 and MafA expression levels were determined after transfection with miRNA mimic or inhibitor by real-time PCR (b) and western blot (c). The expression level in the control group was respectively set as 1, *P＜0.05 vs. the control group; In (c), a: control, b: miR-128 mimic, c: miR-128 inhibitor, d: miR-216a mimic, e: miR-216a inhibitor
