Abstract

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 through anastomosis to investigate alloimmune-induced vascular rejection.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. Use Balb/cYJ (H2d) donor mice and C57Bl/6 (H2b) recipient mice to examine allogeneic reactions. Mice are used for experiments between the ages of 8 to 12 weeks. Use either female or male mice. Syngeneic controls consist of aortic segments from C57Bl/6 donors into C57Bl/6 recipients. 1. Donor and …
