RUNX2 immunostaining images (green), nuclei (blue) and actin (red) of MC3T3-E1 on 3D printed scaffolds A) in basal media and B) in osteogenic media. C) Relative quantification of RUNX2 after 14 days of culture (n = 3). (** < 0.01 and * < 0.05 show statistical significance between the groups at the same media and ## < 0.01 and # < 0.05 show statistical significance between samples cultured in different media).
