Figure 2. Transforming growth factor β in normal human corneas and pseudophakic bullous keratopathy corneas. The expression of transforming growth factor -β1, transforming growth factor -β2, and transforming growth factor -β3 isoforms in (A) normal human corneas (Kruskal–Wallis one-way analysis of variance test; p=0.0003) and (B) pseudophakic bullous keratopathy corneas (Kruskal–Wallis one-way analysis of variance test; p<0.0001). C: Comparison of transforming growth factor -β3 gene expression between pseudophakic bullous keratopathy and normal corneas (Mann–Whitney U test, p=0.0107).
