Comparative Aging Pathology Program (CPA-P)

Welcome to the Comparative Pathology of Aging Program in the Department of Comparative Medicine at the School of Medicine, University of Washington.  The program is directed by Jessica M. Snyder DVM, MS, DACVIM (Neurology).  The mission of the program is to provide a comprehensive and collaborative aging pathology resource for investigative groups and trainees performing preclinical studies and discovery research in aging animal models.

Specialized testing for this program is performed through the Histology and Imaging Core at South Lake Union and includes evaluation of necropsy and histology samples by state-of-the-art methods including histology and histochemical staining, immunohistochemistry, microscopy and digital imaging, and image analysis and morphometry.


  • Project consultation during initial study design, execution, analysis, and publication preparation
  • Concise morphologic diagnoses using standardized consensus nomenclature
  • Standardized scoring systems for neoplastic, inflammatory, and other non-neoplastic lesions
  • Cause of death assignments, co-morbidity and disease burden quantification
  • Customized methods development for project-specific pathology objectives
  • Publication quality photomicrographs and virtual slide annotation
  • Comparison and validation of rodent models to human conditions


State of the art Histology, Immunohistochemistry and Digital Microscopy technologies are utilized at the HIC.  Click here for a list of equipment.
