Immunofluorescence analysis results of wound healing status after treatment of ocular alkaline burn wound with 4D-CTH encapsulating rLESC-enriched limbal epithelium. Cytokeratin 3 and 12 (red) and vimentin (green) were used as markers of the epithelial and stromal cells, respectively, in the unburned (normal), untreated (model), 4D-CTH treated, traditionally treated, and 4D-CTH-rLESC treated alkali burned rat corneas. Scale bars = 100 μm
