Physical properties of CHA scaffolds. (a) Macroscale photograph of D-PBS-hydrated CHA scaffolds (left to right: 2% CHA, 4% CHA, 8% CHA). Scanning electron micrographs of (b-c)_2% CHA, (d-e) 4% CHA, and (f-g) 8% CHA scaffolds depicting a highly porous microstructure. Scale bars represent (a) 4 mm, (b, d, f) 300 μm, and (c, e, g) 100 μm. (h) Apparent density of CHA scaffolds presented as mean ± SD (n = 8). (i) Total scaffold porosity presented as mean ± SD (n = 12). (j) Pore area of CHA scaffolds (n ≥ 90) where “+” denotes mean pore size. P-values were calculated using one-way ANOVA where (*) indicates a significant difference from all other conditions (p ≤ 0.05).
