The severe organ shortage has resulted in increased use of marginal kidney grafts for transplantation. This has triggered interest in alternative storage methods, since marginal grafts especially tolerate cold storage poorly. The technique of normothermic ex vivo kidney perfusion (NEVKP) represents a novel preservation method for kidney grafts prior to transplantation.

We describe a technique in which a section of the abdominal aorta from a mouse is transplanted orthotopically to just below the renal arteries in an allogeneic or syngeneic recipient. This technique can be useful in studies in which transplantation of large arteries of uniform size is deemed advantageous.

This video describes orthotopic kidney auto-transplantation in a porcine model. This surgical procedure involves the transplantation of an animal's kidney graft at its original anatomical location. The model is used to investigate new treatments for end-stage kidney diseases in humans.
FAQs
Recipient immune cells can identify donor antigens on a biological graft as foreign. This recognition activates inflammatory pathways, and that inflammation can injure the graft tissue. The mechanism shows why successful transplantation depends on more than surgical replacement: the recipient’s immune response must remain sufficiently controlled to support graft acceptance during ongoing care.
Immunosuppressive therapy may reduce immune activity directed against donor tissue and thereby limit rejection-related graft damage. However, suppressing immunity also weakens defenses against infection. Care therefore requires a balance between protecting the graft from inflammatory injury and maintaining enough host defense for microbial control, rather than treating immune suppression as an unqualified benefit.
Donor antigens provide the recognition signals that allow recipient immune cells to distinguish biological graft tissue as foreign. Their recognition connects the transplanted material to inflammatory injury and possible rejection. This immunologic feature makes biological graft acceptance a central concern in research and patient management, alongside the procedure’s vascular purpose.
The same immune system that can damage donor tissue also helps defend the recipient against microbes. Reducing immune activity may support graft acceptance, but it can weaken microbial control. This interaction makes infection management part of the transplantation strategy, requiring attention to both immune-mediated graft injury and the consequences of reduced host defenses.
Graft monitoring should consider whether inflammatory immune activity is harming the transplanted tissue and whether weakened defenses are allowing infection-related problems to emerge. These concerns provide complementary information about graft acceptance and microbial control. Monitoring therefore supports decisions about ongoing immunosuppressive therapy, antimicrobial management, and the patient’s long-term care.
Antimicrobial management addresses the infection risk created when immunosuppressive therapy weakens normal defenses. It must be considered alongside efforts to limit immune-mediated graft damage, because focusing on only one threat can compromise the other goal. In this context, antimicrobial planning is part of maintaining graft function and supporting safer long-term follow-up.
This procedure provides a model for studying how donor antigens, inflammatory pathways, immunosuppressive therapy, and microbial control interact in a clinically important setting. It is especially relevant to complex aortic disease, where researchers and care teams must connect graft monitoring with antimicrobial management and strategies that promote acceptance without overlooking infection risk.
