[Retracted] The Favorable Effect of Mesenchymal Stem Cell Treatment on the Antioxidant Protective Mechanism in the Corneal Epithelium and Renewal of Corneal Optical Properties Changed after Alkali Burns

Figure 5

The expression of VEGF in injured and stem cell treated corneas on day 15 after the injury. VEGF expression is high in untreated corneas (a) and Nano-treated corneas (b) and less expressed in Ad-MSCs treated corneas (d). After the treatment of corneas with BM-MSCs (c) and LSCs (e), the expression of VEGF is low. In control corneas (f) the expression of VEGF is absent. The sections are counterstained with hematoxylin. Scale bars: 50 μm. The expression of genes for VEGF (g) on day 15 after the injury was determined by real-time PCR. Each bar represents the mean ± SD from 6 individual corneas. The values with asterisks represent a statistically significant () difference from untreated injured corneas.
