Fig. 2. Distribution of TfR and Fpn in the anterior segment of bovine eye:

Fig. 2.

(A) The reaction for TfR is evident on the ciliary epithelium facing the AH (panel 1). TfR is localized on the apical membrane and intracellular vesicles of NPE cells as in the human sample (panel 2). The corneal epithelium does not react for TfR (panel 3), while the corneal endothelium shows a distinct reaction on the plasma membrane (panel 4). H&E staining shows multiple layers of corneal epithelium, the stroma, and a single layer of corneal endothelium (panel 5). Scale bar: 25 μm. (B) Fpn is expressed on the ciliary epithelium and the iris (panel 1). The expression of Fpn is limited to NPE cells as in the human sample (panel 2). H&E staining shows the orientation of ciliary epithelium with respect to the iris and AH (panel 3). Unlike human samples, the bovine corneal epithelium did not react for Fpn (panel 4). However, corneal endothelium showed strong reactivity for Fpn (panel 5). Scale bar: 25 μm.
