Comparative Pathology Core
What We Do
The Penn Vet Comparative Pathology Core (CPC) is a shared resource of the Abramson Cancer Center, offering expertise in veterinary pathology and advanced services in histology, molecular staining, and digital pathology. Staffed by board-certified veterinary pathologists, the CPC provides expert pathological characterization and validation of animal models used in biomedical research. By providing a comprehensive analysis of tissue samples, the CPC supports the identification of therapeutic targets and relevant biomarkers in translational research studies and clinical trials, helping bridge the gap between preclinical discoveries and clinical applications.

Importance of Clinical Trials
Clinical trials are a crucial step in the often cyclical “benchtop to bedside” process of translating clinical questions into laboratory research and then into patient care.
