Figure 5.

The MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay was used to measure the cell viability of stromal and epithelial cells co-cultured with the electrospun polyglycolic acid (PGA) scaffold or the fibrin-agarose scaffold. The MTT optical density of both the PGA and fibrin-agarose scaffolds seeded with stromal and epithelial cells increased during 7 days of cell culture. The cell viability did not show any significant between-group differences over time (p≥0.05).
