Alkaline phosphatase activity of BM-MSCs (A) and UC MSCs (B) cultured on the 3D-printed HA (HA) and coated 3D-printed HA (coated HA) compared with those cultured on a plastic culture plate at days 3, 7, 14, 21, and 28. N = 3, *P < 0.05, compared to MSCs cultured with DMEM + 10%FBS. #P < 0.05, compared to MSCs cultured with osteogenic differentiation medium on 3D-printed HA. $P < 0.05 compared to MSCs cultured with osteogenic differentiation medium on a plastic culture plate.
