Immunohistochemical features of a bovine ovary with squamous metaplasia of the rete ovarii. (A) Expression of low molecular weight cytokeratin 7 (clone OV-TL 12/30) in an area of double layered cuboidal non keratinized epithelium. (B) Ovary, cow. Absence of expression of low molecular weight cytokeratin 7 (clone OV-TL 12/30) in an area of keratinizing stratified squamous epithelium. (C) Low levels of expression of high molecular weight cytokeratins 1, 5, 10, and 14 (clone 34BE12) in an area of double layered cuboidal non keratinized epithelium. (D) Strong expression of high molecular weight cytokeratins 1, 5, 10, and 14 (clone 34BE12) in an area of keratinizing stratified squamous epithelium. Streptavidin-biotin-peroxidase, Hematoxylin counterstain.
