FIG. 3. — The effect of electrospun nanofiber diameter and scaffold microstructure on biological response. TiO₂ scaffolds with 6% PVP (A) had smaller fiber diameters than TiO₂ scaffolds with 10% PVP (B). TiO₂ scaffolds with 10% PVP that were additionally micropatterned (C) induced the highest osteocalcin levels by osteoblasts (D). Statistical significance determined by p value of <0.05; * vs. all TiO₂ groups; # vs. flat side of the same formulation; $ vs. 6% PVP of the same side. PVP, polyvinylpyrrolidone.
