Effects of silk fibroin solution sterilization upon the mechanical properties of the scaffold. (A) Stress-strain curve and (B) compressive modulus of silk fibroin scaffolds formed from non-sterilized silk fibroin compared to scaffolds formed with silk fibroin that has been sterilized by either filtration or autoclaving. Scaffolds were tested under compressive loading in physiological temperature and pH conditions (PBS, pH 7.4, 37°C). n≥4, *** p<0.001.
