In vitro degradation, and protein loading and release of scaffolds. (A) Weight changes of three composite scaffolds during degradation. (B) Alteration of pH value in medium during scaffold degradation. (C) Routine scan and 3D reconstruction micro-CT images of PLGA/nHA₁₀, PLGA/nHA₃₀, and PLGA/nHA₃₀^BSA after 42 days of degradation. Scale bar = 2 mm (D) Protein loading rates of PLGA/nHA₃₀ and PLGA/nHA₃₀^PDA (E) Accumulated release of BSA-FITC from PLGA/nHA₃₀^BSA. Data are represented as mean ± SD (n = 3; *P < 0.05, ***P < 0.001).
