Real-time RT-PCR illustrates the expressions of osteogenic markers, RUNX-2, osterix (OSX), and osteocalcin (OCN) in BM-MSCs (A, B, C) and UC-MSCs (D, E, F) during cultured on a plastic culture plate, the 3D-printed HA (HA) and coated 3D-printed HA (coated HA). MSCs cultured in complete DMEM medium at day 0 serve as the control. *Statistically significant data with P < 0.05 compared to control. N = 3, #P < 0.05 compared to MSCs cultured on 3D-printed HA at the same time point. $P < 0.05 compared to MSCs cultured on a plastic culture plate at the same time point.
