    Area of Science:

    • Surgical transplantation
    • Immunology
    • Human organ physiology

    Background:

    • The human appendix's function remains incompletely understood.
    • Previous experimental models lacked reproducibility and physiological relevance.

    Purpose of the Study:

    • To describe a simple, reproducible experimental model for studying the normally functioning human appendix.
    • To provide a platform for investigating appendiceal pathophysiology and drug effects.

    Main Methods:

    • Human appendix explantation and subsequent transplantation into immunodeficient nude mice.
    • Maintenance of appendix viability for a minimum of 4 hours post-transplantation.

    Main Results:

    • The model successfully maintains the human appendix in a vital state for experimental study.

  • The transplanted appendix retains normal tissue type and characteristics.
  • Results are quantifiable, and paired controls are feasible within the experimental animal.

    • Conclusions:

    • This xenotransplantation model offers a significant improvement over existing methods.
    • It provides a valuable tool for understanding human appendix function, disease, and therapeutic interventions.
