Executive Industry Relevance

Reliable procurement and preservation of porcine pancreata are critical for generating high-quality islets to support xenotransplantation research and scalable islet supply. Minimizing warm-ischemia and mechanical injury during organ isolation directly impacts islet viability, yield, and downstream translational potential. This protocol addresses a key bottleneck in the preclinical pipeline for diabetes cell therapy innovation and portfolio expansion.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables robust interrogation of islet biology in a controlled, reproducible system.
• Supports functional validation of porcine islets for xenotransplantation feasibility studies.
• Facilitates mechanistic de-risking by preserving islet integrity for downstream assays.

Screening & Assay Development

• Provides standardized, high-viability islets for assay development and compound screening.
• Improves reproducibility and quantitative assessment of islet function and viability.
• Enables scalable preparation of biological material for repeated experimental workflows.

Translational & Preclinical Research

• Aligns with disease-relevant models for diabetes and cell therapy research.
• Ensures continuity from islet procurement through preclinical transplantation studies.
• Reduces biological variability, supporting risk-adjusted advancement decisions.
