Characterization of TGF-β1@CS/BMP-2@SF and 15% TGF-β1@CS/BMP-2@SF. a Water absorption of TGF-β1@CS/BMP-2@SF of different concentrations. b In vitro degradation of TGF-β1@CS/BMP-2@SF of different concentrations. c Water absorption of 15% TGF-β1@CS/BMP-2@SF. d In vitro degradation of 15% TGF-β1@CS/BMP-2@SF. e In vitro release of TGF-β1 and BMP-2 from 15% TGF-β1@CS/BMP-2@SF. The results were measurement data and expressed as mean ± standard deviation derived from at least 3 independent experiments. Data comparison at different time points was analyzed by Bonferroni-corrected repeated measures ANOVA
