Table 2. Distribution of S100 proteins in normal corneal, limbal epithelia and SCC tissue.
| Protein | Cornea | Limbus | SCC |
|---|---|---|---|
| S100A2 | Negative | Plasma
membrane of basal epithelial cells, decreasing progressively toward upper layers. |
Overexpressed in all epithelial cells. |
| S100A6 | Plasma membrane of all cells | ||
| S100A8/9 | Negative | Located at the surface of the limbal epithelium. | Top
layer cells of the epithelium, decreasing progressively toward the stroma and disappeared at the basal layer. |
| S100A10 | Negative | Nucleus
of limbal epithelial cells, decreasing progressively toward upper layers. |
Nuclear staining of all epithelial cells. |
| S100A11 | Negative | Plasma
membrane staining of upper layer cells adjacent to the conjunctiva. |
Uniform staining of all epithelial cells. |
