Abstract
Myoepithelial cells (MECs) are known to play an active role in mixed mammary tumors and are found in dogs as well as in humans. The study aimed to assess the morphologic features of epithelial and mesenchymal cells and MECs and investigate their roles in epithelial-mesenchymal transformation in different tumor types in canine mammary tumors. Immunohistochemical staining was performed on 165 specimens from benign mixed tumors (BMT), carcinosarcomas, and simple carcinomas (SC). Double immunohistochemical staining was for the antigen pairs p63/actin, p63/vimentin, p63/CK19, p63/CK8, p63/CK14. BMP6 was demonstrated only by single immunostaining. For BMP6, epithelial cells were positive in BMTs, carcinosarcomas, and SCs. Myoepithelial cells were variably positive for p63, actin, vimentin, and CK14. Epithelial cells were usually positive for CK19 and CK8. MECs include both epithelial and mesenchymal components, so metaplasia in epithelial cells can also form in MECs, and these two cell types should be evaluated together.
期刊介绍：
Biotechnic & Histochemistry (formerly Stain technology) is the
official publication of the Biological Stain Commission. The journal has been in continuous publication since 1926.
Biotechnic & Histochemistry is an interdisciplinary journal that embraces all aspects of techniques for visualizing biological processes and entities in cells, tissues and organisms; papers that describe experimental work that employs such investigative methods are appropriate for publication as well.
Papers concerning topics as diverse as applications of histochemistry, immunohistochemistry, in situ hybridization, cytochemical probes, autoradiography, light and electron microscopy, tissue culture, in vivo and in vitro studies, image analysis, cytogenetics, automation or computerization of investigative procedures and other investigative approaches are appropriate for publication regardless of their length. Letters to the Editor and review articles concerning topics of special and current interest also are welcome.
