Figure 4

Colocalization of importin 13 and keratin 17 in the epithelium of the pterygium. Representative images of double immunofluorescence staining of importin 13 (IPO13; green) and keratin 17 (K17; red) in the normal conjunctiva, primary pterygium, and recurrent pterygium. A–D demonstrate normal conjunctiva. E–H demonstrate primary pterygium. I-L demonstrate recurrent pterygium. IPO13 was colocalized with K17 in the basal layer of the conjunctiva and the epithelium of the pterygium (as arrows indicated). Scale bar: 50 μm.
