Quantitative real-time RT-PCR showed the expression of miR-21, miR-27b, miR-29a, and let-7b during osteogenic differentiation of high- and low-osteogenic UC-hMSCs. UC-hMSCs cultured in DMEM + 10%FBS served as control. Data are presented as mean ± SEM (n = 3). *p < 0.05 compared to low-osteogenic UC-hMSCs cultured in OstDiff medium on day 7, #p < 0.05 compared to high-osteogenic UC-hMSCs cultured in OstDiff medium on day 7 and $p < 0.05 compared to low-osteogenic UC-hMSCs cultured in OstDiff medium on the same day.
