Effect of silk fibroin on lipid peroxidation in isolated fibroblast and Huvec cells. Fibroblast and Huvec cells (1 × 106 cells) were incubated for 6, 12 and 18 h with various concentrations of silk fibroin (0.5, 1 and 2 mg/mL). Data represented as mean ± SD of data determined from three separate experiments
