Figure 2. Effect of plioglitazone on corneal fibroblast cell motility. A monolayer of confluent corneal fibroblasts was scraped with a sterile pipette tip after being preincubated with increasing concentrations of pioglitazone (1, 3, and 10 μm) for 24 h. Wound closure was observed by phase-contrast microscopy and photographed at 0, 24, 48, and 72 h. A: Photographs of one representative experiment. B: Graphic representation of the mean of four experiments. For each sample, the result is expressed as percentage of the wound width at the start of the experiment. The asterisk indicates p<0.05 versus the control group
