The first critical step in the VX2 tumor methodology is successful propagation of a tumor in the hind limb of a donor rabbit. Refer to the first paragraph in the &#34;Representative Results&#34; section for more information regarding this step.
The next critical step is ensuring that the viable tumor capsule is properly identified. Not only will this be necessary for tumor suspension preparation, but it is also important for selecting and generating tumor pieces for hepatic implantation. The d...

The rabbit VX2 tumor model has played a role in experimental oncology since its development in 19351,2. This tumor is a virus-induced anaplastic squamous cell carcinoma characterized by hypervascularity, rapid growth, and easy propagation in skeletal muscle3,4. While the rabbit VX2 tumor model has been used to investigate a multitude of cancers5,6,7,8; the focus of this paper is liver cancer9.
The purpose of the method described is to present a model for primary liver cancer, or hepatocellular carcinoma (HCC), that can be used by Interventional Radiologists for translational research. It can be used for pharmacokinetic studies, therapeutic investigations, and ablative method testing10,11,12,13,14,15.
The method detailed herein yields multiple advantages over other models within the same sphere such as rodent models like rats, mice, and woodchucks, or larger models like primates16. One of the primary benefits is the rapid and reliable tumor growth which allows researchers to establish an active tumor line within a month of first hind limb propagation17. Additionally, this tumor has straightforward sonographic visibility and a hypervascular periphery which allows for both transarterial locoregional treatments and ablative therapies. Finally, and most importantly, the size of the rabbit vasculature permits feasible and technically easy utilization of vascular instrumentation18.

development and angiographic use of the rabbit vx2 model for liver cancer

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 na&#239;ve 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.

When looking at Figure 1, it is clear that the quadricep of the rabbit is enlarged. Additionally, multiple small discrete nodules, typically correlating with tumor growth through the fascia, are visible. Upon palpation, the injected limb should appear than the non-injected limb. If a researcher requires more definitive assurance of tumor presence, ultrasound imaging can be used to identify the tumor embedded in the muscle. If a tumor is not detected, the hind...
