MTS assay of PE, PE/WG and PE/WG/TiO2. Samples with size of 0.5 cm * 0.5 cm were cut and placed in the 96 well plates. The scaffold was seeded with fibroblast cells with 10 × 103 cells/cm2 density and cultured for 5 days. After 5 days, the medium was added with 20% of MTS reagent for 4 h and optical density (OD) was measured at 490 nm.
