We describe protocols for our mouse graft arteriosclerois (GA) models which involve interposition of a mouse vessel segment into a recipient of the same inbred strain. By backcrossing additional genetic changes into the vessel donor, the model can assess the effect of specific genes on GA.

To improve our knowledge of cellular and molecular neotissue formation, a murine model of the TEVG was recently developed. The grafts were implanted as infrarenal vena cava interposition grafts in C57BL/6 mice. This model achieves similar results to those achieved in our clinical investigation, but over a far shortened time-course.

Full-root aortic valve replacement by stentless aortic xenograft is a viable option in patients with small aortic roots. We describe, a technique for the full-root implantation of stentless aortic xenografts, with emphasis on the management of the proximal suture line and coronary anastomoses, and discuss its limitations and alternative options.

A Mouse Aortic Interposition Model to Study Alloimmune-Induced Vascular Rejection

This video demonstrates a method for generating a mouse aortic interposition model to study alloimmune-induced vascular rejection. After placing an anesthetized donor mouse in the supine position, the infrarenal abdominal aorta (IAA) is carefully isolated from surrounding structures. Branching vessels are ligated, and both ends of the IAA are clamped to prevent blood flow before resection. Subsequently, the donor IAA is implanted into an allogeneic recipient mouse, and blood flow is restored...

A Technique for Human Skin Grafting in a Mouse Model

This video demonstrates a method for grafting human skin onto an immunodeficient mouse with a suppressed neutrophil response. The method involves applying human split-thickness skin to the mouse's graft bed, sealing it, and covering it for recovery. Eventually, the human skin adheres to the mouse's skin, establishing vascularization and circulation, resulting in a successful skin xenograft.
FAQs
Blood flow makes the graft a biologically active test environment rather than a static implanted sample. Once circulation is restored through the anastomoses, the vessel experiences hemodynamic forces while remaining exposed to immune surveillance. These influences can drive tissue remodeling, so investigators can examine how mechanical and immune conditions jointly shape graft behavior over time.
Donor and recipient characteristics provide important experimental variables in a mouse aortic graft. Researchers can place the vessel under controlled genetic conditions and compare treatment conditions, helping separate responses linked to transplantation from those associated with a particular intervention or biological background. This design is useful for testing mechanisms and identifying changes that may be treatment-sensitive.
Time-course observation is central to interpreting this model. Structural findings show how the graft changes physically, while molecular measurements reveal associated biological responses. Examining both types of evidence can help investigators follow processes such as rejection, inflammation, healing, or remodeling instead of relying on a single endpoint. The combined readout supports more complete analysis of vascular responses.
Establishing a functioning graft depends on precise microvascular anastomoses that connect the transferred aortic segment to the recipient circulation. The critical outcome of this surgical connection is restored blood flow through the graft, which enables subsequent study of vascular and immune responses. Because microsurgical connection is essential, experimental interpretation depends on whether this circulation is successfully established.
Researchers use mouse aortic grafts to model several clinically relevant vascular processes, including transplant rejection, vascular inflammation, atherosclerosis, aneurysm development, and graft healing. The same general platform can therefore address both transplant medicine and broader vascular disease biology. Its value lies in observing these responses in a living circulating vessel under controlled experimental conditions.
In medicine, the model helps connect disease mechanisms with therapeutic evaluation. Investigators can impose defined genetic or treatment conditions, then monitor structural and molecular changes in the graft over time. Those observations provide evidence about how an intervention or biological context affects vascular pathology, immune-related graft responses, or repair, supporting assessment of potential therapies for vascular and transplant disorders.
