Immunohistochemical detection of H-sema E protein in human tissues. (A) Immunoperoxidase staining of H-sema E in Schwann cells of a peripheral nerve (Left) and the spinal cord (Right). (B) Hematoxylin and eosin staining of skin from the foot showing keratinization. (C) Immunoperoxidase staining of H-sema E in a section adjacent to the section shown in B. (D) Immunoperoxidase staining of H-sema E in a nest of an untreated pharyngeal cancer. Only parakeratotic cancer cells in the center of the nest are stained. (E) Hematoxylin and eosin staining of a section adjacent to the section shown in D. (F) Immunoperoxidase staining of H-sema E in a recurrent tumor taken from the same patient as the tissue in D. (G) Immunoperoxidase staining of H-sema E in untreated lung cancer with coagulation necrosis (∗). (H) Immunoperoxidase staining of H-sema E in bizarre giant cells in a recurrent lung cancer after treatment.
