[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 6

Corneal opacity of alkali-injured and stem cell treated eyes. Representative photographs show a control healthy eye (a), alkali-injured eye (immediately after the injury) (b), the injured eye with sutured nanofiber scaffold (immediately after the injury) (c), and injured eyes on day 15 after the injury which were untreated (d) or treated with cell-free nanofiber scaffold (e) or with nanofiber scaffolds seeded with BM-MSCs (f), Ad-MSCs (g), or LSCs (h). Corneal neovascularization is strongly expressed in untreated corneas ((d) arrows) and highly suppressed in corneas treated with nanofiber scaffolds BM-MSCs (f) and LSCs (h). The quantification of corneal neovascularization is shown in (i). Each bar represents the mean ± SD from 6 corneas. The values with asterisks are significantly different () from untreated injured corneas.
