Standardizing training protocol of an intestinal transplantation model: A learning curve study

Area of Science:

• Surgical research
• Transplantation biology
• Animal models

Background:

• Rodent models are vital for studying intestinal transplantation, including ischemia-reperfusion injury, rejection, and tolerance.
• These models facilitate the development of therapeutics for improved long-term transplant survival.
• Translating laboratory findings into clinical applications is the ultimate goal.

Purpose of the Study:

• To provide a comprehensive guide for establishing successful rat intestinal transplantation models.
• To outline key steps from microsurgical training to postoperative care.
• To serve as a resource for research groups aiming to implement these models.

Main Methods:

• Detailed microsurgical techniques for graft procurement and implantation.
• Recipient postoperative care protocols.
• Establishment of orthotopic and heterotopic transplant models in rats.

Main Results:

• Achieved 83% survival in orthotopic and 85% in heterotopic rat intestinal transplants.
• Success rates are comparable to leading research groups globally.
• The described methods ensure reproducible and successful outcomes.

Conclusions:

• This manuscript offers a detailed protocol for rat intestinal transplantation.
• The guide aims to empower researchers in establishing robust experimental models.
• Successful implementation of these models will advance intestinal transplantation research and clinical practice.
