Fig. 5.

Analysis of specific markers of the epithelial cells of the human cornea and limbus in control human native corneas (CTR-C), control human native scleral limbi (CTR-L), and human artificial corneas (HAC) using immunohistochemistry. Three samples were analyzed per type of tissue (n = 3). KRT3, cytokeratin 3; KRT19, cytokeratin 19; KRT15, cytokeratin 15; ΔNp63, limbal isoform of the protein p63. Higher magnification inserts at the bottom of the image correspond to the areas highlighted with dotted red squares in the HAC tissues. Scale bars: 50 μm
