Gall bladder mucosal epithelial hyalinosis

Research Services

Welcome to the Comparative Pathology Laboratory, where our team of experts stands ready to support your research endeavors. We provide a comprehensive range of services with the mission to aid investigators using animal models of disease and interventional therapeutics. Services are available for intramural (University of California) and extramural investigators. Our vast array of services include:

•           Necropsy services for research study animals, including gross dissection of target tissues, high-quality photo documentation, histological processing, pathology interpretation and training of investigators in animal necropsy.

•           Pathology services including histopathology evaluation and interpretation of tissues, scoring and semi-quantitative data analysis, and photomicroscopy, conducted by board-certified veterinary pathologists (American College of Veterinary Pathologists) experienced in multiple areas including geropathology and aging, infectious diseases, models of immunotherapy and humanized mice (including CAR T cells), genetic therapy (including AAV), oncology, degenerative diseases, among many others.

•           Morphological phenotyping of rodents (including novel genetic engineered mouse (GEM) models) and other non-rodent experimental animals, including full necropsy, organ weight, clinical pathology, and histopathology interpretation.

•           Pre-study consultation services covering experimental design and planning, animal modeling and optimal sample collection strategies.

•           Generation of publication-ready figures, text, and graphics to enhance the scientific quality and dissemination of research findings.

•           Clinical pathology services including hematology, clinical chemistry panels, serology, molecular diagnosis (PCR), parasitology and microbiology, all validated for mouse and other research species. Subsequent processing of these specimens and downstream assays are also available.

For further information on how we can support your project, please reach out to us at cpl-projects@ucdavis.eduWe look forward to collaborating with you.
