Figure 6. Cell viability is not influenced by treatment with pioglitazone. After treatment with medium alone, or with pioglitazone at 0.1, 1, 3, and 10 μm, respectively, for 72 h, the viability of corneal fibroblasts was measured by MTT assay. Results are shown as percentages of the control (untreated cells). There was no significant difference between any treatment (ANOVA) p>0.05 versus control.
