Abstract
The rabbit VX2 tumor is an animal model commonly utilized for translational research regarding hepatocellular carcinoma (HCC) in the field of Interventional Radiology. This model employs an anaplastic squamous cell carcinoma that is easily and reliably propagated in the skeletal muscle of donor rabbits for eventual harvest and allograft implantation into the liver of naïve recipients. This tumor graft rapidly grows within the liver of recipient rabbits into an angiographically identifiable tumor characterized by a necrotic core surrounded by a viable hypervascular capsule. The physical size of the rabbit anatomy is sufficient to facilitate vascular instrumentation allowing for the application and testing of various interventional techniques. Despite these benefits, there exists a paucity of technical resources to act as a concrete reference for researchers working with the model. Herein, we present a comprehensive visual outline for the technical aspects of development, growth, propagation, and angiographic utilization of the rabbit VX2 tumor model for use by novice and experienced researchers alike.
