SEM morphology of 3D-printed PEKK and hSF-MSCs cultured on the surface of PEKK scaffolds. (a,d) The porous topography of PEKK scaffolds after 7 days of being immersed in culture media. (b,e,f) hSF-MSCs attached on PEKK scaffolds after 7-day incubation. Note: The red arrows indicate the filopodia, and the white rectangles indicate the lamellipodia of hSF-MSCs. (c) Cell growth curve of hSF-MSCs on PEKK versus TCP. Data are presented as mean ± SE. Differences were considered significant at *p < 0.05.
