Overview

Endpoint’s pathology services deliver evaluation, oversight, and consultative support across the full scope of preclinical research. Our pathologists contribute not only essential readouts but also critical guidance during study planning, where early input improves endpoint selection, tissue collection, and specimen processing. We also provide independent peer review for regulatory submissions, ensuring accuracy, clarity, and confidence in study outcomes.

Our expertise spans anatomic and digital pathology evaluations, image-based biomarker analysis, and necropsy oversight across efficacy, safety, biodistribution, device–tissue interaction, and neurotoxicity studies. We also support analysis of novel models and non-traditional endpoints. These services apply to a wide range of biomedical products—including biomolecules, cell and gene therapies, medical devices, small molecules, and stem cells—helping programs align with translational goals and regulatory expectations.

Service Highlights

Below is a selection of our pathology offerings. If you don’t see exactly what you need, please contact us — we can likely tailor a solution for your program.

  • Necropsy Oversight & Tissue Collection: Leadership during necropsy to ensure correct sampling, preservation, and processing. Training and guidance available to study teams to safeguard downstream analyses.
  • Histopathology & Digital Analysis: Comprehensive tissue evaluation supported by whole slide scanning, semi-quantitative lesion scoring, and quantitative assessment (morphometrics and AI/ML image analysis).
  • Image-Based Biomarkers: Design and application of brightfield and fluorescent IHC/ISH, including multiplex staining. Quantitative workflows support biomarker discovery, mechanistic studies, biodistribution, and device performance evaluations.
  • Advanced & Novel Applications: Expertise in specialized and less commonly studied organs and tissues — including but not limited to ganglia, tendons, and unique models like non-mammalian vertebrates and various new approach methodologies (NAMs).
  • Data Analysis & Reporting: Integration of pathology findings with study data to prepare clear and concise reports, statistical outputs (when warranted), and decision-ready summaries. Deliverables are structured to support regulatory submissions for many biomedical products.
  • Peer Review & Independent Assessment: Independent peer review of pathology data sets and reports, including formal peer review for regulatory submissions, thereby providing increased confidence in outcomes.
  • Toxicologic Neuropathology: Specialized evaluation of neural tissues, including brain, spinal cord, ganglia, and peripheral nerves. Services include lesion identification and characterization, interpretation, and pathology peer review.

Why Endpoint?

Pathology at Endpoint is closely connected to other services, ensuring that findings are not assessed in isolation but are actively used to optimize study design and interpretation. By integrating pathology with surgical, model development, and toxicology expertise, Endpoint helps reduce rework, improve reproducibility, and deliver cohesive datasets. This collaborative model ensures that pathology insights contribute directly to advancing both therapeutic and device study objectives.
