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.
