Xenotransplantation studies have been a backbone of oncology research for four decades, and provide an effective research and evaluation environment for novel pharmaceutical compounds. Typically, these studies involve the implantation of tumorigenic human cell lines into immunocompromised mice, providing scientists with an in vivo model of tumor behavior in which to perform experiments including screening of novel cancer therapies, studies of cell behavior, and examination of metastasis. Patient-derived xenografts are a fundamental part of in vivo pharmacological research, aiding in the translation from benchtop to bedside.

Liver cancer, or hepatic carcinoma, symptoms include a painful lump on the right side under the rib cage, abdomen swelling, yellowing of the skin, weight loss and easy bruising. Causes include hepatitis B induced cirrhosis, hepatitis C, alcohol, aflatoxin, liver flukes and non-alcoholic fatty liver disease. Types of liver cancer are hepatocellular carcinoma (HCC, the primary type), cholangiocarcinoma, mucinous cystic neoplasm as well as intraductal papillary biliary neoplasm. Detection typically happens via body imaging systems such as ultrasound or MRI or CT scans; tumor markers in the blood such as alpha-fetoprotein (AFP), carbohydrate antigen 19-9 or carcinoembryonic antigen (CEA) can also help with hepatic cancer detection. Treatments include surgical resection, liver transplantation, systemic chemotherapies (uncommonly used) and percutaneous ablation. The liver is generally not tolerant to radiotherapy.

Using human xenograft models of hepatic cancer, as previously mentioned, is a powerful research tool, and there are many models of liver cancer to choose from. There are links above to some of the most common tissue culture models that Altogen Labs has available, summarized in the table below. Models are often selected based on morphology, genetics, histology, early vs. late stage phenotype, invasive/aggressive properties, and abnormal protein expressions (usually relating to cell cycle, apoptosis, growth and angiogenesis). The goal of xenografts and murine models is to mirror human pathology and disease as closely as possible so that accurate insights into cellular events are achieved. This aspect is particularly critical with preclinical drug testing for accurately evaluating compound efficacy.

About the models

CD1

This model originates from a non-inbred Swiss stock of the 1920s from the Centre Anticancerux Romand (Lausanne, Switzerland). Outbred stocks are generally used for their genetic variability.

B6

This strain of mouse arose from a spontaneous mutation in the C57BL/6 strain resulting in a coisogenic albino mutant. These mice have a mutant tyrosinase gene.

Balb/c

This strain of nude mouse was developed in the 1980s through many crosses and backcrosses and remains to be an inbred model. Balb/c mice do not have a thymus and therefore cannot produce T-cells and are considered immunodeficient. Balb/c mice are often used for their easy breeding and similar weights (low-variation) of males and females. They are also used for monoclonal antibody production.

Balb/SCID

This mouse model lacks functioning T and B cells but do have functioning NK cells which limits engraftment. These mice are sensitive to irradiation and have functioning macrophages, dendritic cells and complement activity. Some cancer cell lines show improved engraftment over nude models in Balb/SCID mice.

NOD/SCID

The homozygous SCID mutation results in impaired T cell and B cell lymphocyte development. The NOD characteristic results in impaired natural killer cell function. NOD/SCID mice also lack macrophage and dendritic cell activity as well as reduced complement activity. These mice have a non-obese diabetic and insulitis background and low cytokine production. NOD/SCID mice exhibit a 36-week median survival due to the development of thymic lymphomas, which limits their use to short-term experiments.

Nu/nu

These mice originate from the National Institute of Health (NIH). Originally thought to be BALB/C congenic mice, once it was discovered that these mice were outbred they were determined to be of their own strain. These mice do not have a thymus, or T-cells, and are nude immunodeficient models.

CD57BL/6

This laboratory mouse strain was the 2nd mammalian species to ever have its genome published in entirety. They originate from the Bussey Institute for Research in Applied Biology in 1921. These mice are often selected for easy breeding and availability of congenic strains. These mice are particularly sensitive to odors, noise, pain, cold, alcohol and morphine addiction.

CB17

CB17 mice are of a congenic strain that carry the immunoglobulin heavy chain allele (Igh-1b) from a C57BL/Ka on a BALB/c background. They are an ideal control for the CB17/SCID immunodeficient mouse model

NSG

Also known as NOD scid gamma, these mice are deficient in NK, T and B cells as well as multiple cytokine pathways. They also have reduced dendritic cell function and defective macrophage activity and lack a complement system. They are one of the most immunodeficient models available and unlike NOD/SCID mice, NSG mice do not develop thymic lymphomas and can be used for long-term experiments.

Swiss Nude

These mice originate from the 1974 Gustave Roussy Institute (Villejuif, France) Swiss stock. They are T cell deficient, nude and albino.
