• To address the challenges of adapting decellularization techniques for large animal anatomy, size, and handling.
• To provide a comprehensive guide including anesthesia, organ harvest, decellularization, and storage, with potential pitfalls.

Main Methods:

• Detailed protocol for decellularization of porcine livers.
• Consideration of anesthesia, organ procurement, and preservation techniques.
• Step-by-step guide for the decellularization process and sample storage.

Main Results:

• An optimized decellularization protocol for large animal livers.
• Identification and mitigation strategies for potential pitfalls during the process.
• A reproducible methodology for generating decellularized liver scaffolds.

Conclusions:

• The described methodology provides an efficient approach for large animal liver decellularization.
