Figure 5

Scanning electron microscopic images demonstrate the characteristics of BM-MSCs and UC-MSCs cultured with osteogenic differentiation medium on 3D-printing HA (HA) and coated 3D-printing HA (coated HA) compared to the cells cultured with complete DMEM medium for 28Â days. The cells attach to the scaffolds and become large-flatten cells with extended and interconnected cytoplasmic processes (red arrow).
