Fabrication and Application of a 3D-Printed Poly-ε-Caprolactone Cage Scaffold for Bone Tissue Engineering

Figure 2

Surface treatment and properties of the treated and untreated scaffolds. (a) Surface roughness of scaffolds treated and untreated with NaOH. Bar represents 100 μm and 10 μm, respectively. (b) Water contact angle images of PCL sheets treated and untreated with NaOH. (c) Summary of the water contact angle. Mean ± SD; n = 3; . (d) Elasticity modulus of PCL scaffolds treated and untreated with NaOH. Mean ± SD; n = 5. (e) Confocal micrographs of hBMMSCs cultured on treated and untreated PCL sheets for 12 h. Phalloidin is colored green. Bar represents 200 μm. (f) Proliferation curves of hBMMSCs cultured on treated and untreated PCL sheets. Mean ± SD; n = 3.
