[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 4

The expression of α-SMA and TGF-β1 in injured and stem cell treated corneas on day 15 after the injury. The expression of α-SMA is high in untreated (a) and Nano-treated (b) corneas, whereas in corneas treated with BM-MSCs (c), Ad-MSCs (d), and LSCs (e) it is low. Compare with control cornea (f), where the expression of α-SMA is absent. The corneal sections are counterstained with hematoxylin. Scale bars: 50 μm. The expression of genes for TGF-β1 (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.
