Applications of immunohistochemistry in rodent tumor pathology
1Tumor Pathology and Pathogenesis Section, National Cancer Institute, Frederick, MD 21701.
Immunohistochemistry can serve as a valuable adjunct to rodent tumor pathology. Specific antigens may be localized to cells and tissues in normal organs, preneoplastic lesions, and benign and malignant tumors. The immunoreactivity of polyclonal and monoclonal antibodies to these antigens provide a more accurate basis for tumor diagnosis and aid in understanding pathogenesis. Ultimately, the application of more precise understanding of tumor histogenesis and diagnosis will lead to more accurate interpretations of tumor incidence data for safety assessment in toxicology.
