Figure 4

Immunohistochemical analyses of prolactin inducible protein (PIP) in the human cornea (A) with corneal epithelium (CE), lacrimal gland (B) and eyelid (C) with Meibomian gland (MG). The antibody reaction is visible by the intracellular red reaction product. Pictures represent meaningful immunohistochemical analyses of sections obtained from 10 different cadavers for each tissue (n = 10). (A,B) and (C) Inlays show higher magnification. Nuclei are counterstained with hemalum (blue). Arrows and Arrowheads accentuate the reactivity localization.
