Figure 4: Biomarkers for human corneal endothelial cells (CECs).

Nine structural or functional proteins were selected because of their specific staining pattern and subcellular location in CECs compared to corneal epithelial, stromal and trabecular meshwork (TM) cells. Except for N-cadherin, none of them was expressed only in CECs, but they all had a distinct pattern specific for CECs. Nuclei were counterstained by Hoechst 33342 (in blue). Scale bar 20 μm.
