Neste artigo, uma descrição detalhada do método é dado que foi relatado recentemente por Ogunwobi e colegas de concretizar a criação de um modelo de camundongo singênico orthotopic de HCC metástase (Figura 2) 3. A taxa de absorção de tumores para este procedimento é geralmente elevada. Nós já observamos uma taxa de take tumor de 100% 3. No entanto, a taxa de absorção pode ser variável dependendo da competência do investigador. Em um experimento recente realizado po...

Hepatocellular carcinoma (HCC) is one of the most lethal cancers, with poor prognosis and low life expectancy. Nearly all cancer-related deaths are due to the metastatic spread of the disease from the originating organ to additional distant organs2-6.HCC progression is a complex process. Therefore, being able to model the tumor microenvironment that is naturally found in metastatic HCC in animal models can prove to be a successful and useful way to reveal relevant mechanisms in humans.7Unfortunately, the mechanisms of cancer metastasis are still largely unclear. Therefore, there is a need to establish animal models that will enable us to elucidate the underlying molecular mechanisms of metastases of cancers such as HCC3,5.
Mouse model systems are a very useful approach for delineating mechanisms and evaluating novel strategies for treatment of metastatic human cancers5,8. The various mouse model systems that presently exist are a testament to efforts of researchers to correctly depict the complexity of the disease5,8,9.
Ogunwobi and colleagues recently used a survival surgical approach to demonstrate establishment of a novel orthotopic syngeneic mouse model for the study of metastasis in HCC3. Their work established a &#8220;patient-like&#8221; mouse model that recapitulates features of aggressive and metastatic HCCs3. They further demonstrated that this mouse model system can be used to study the biology of circulating tumor cells, and that this holds potential for gaining novel insights into the mechanisms of cancer metastasis3.
The aim of this paper is to describe in detail the methodology used in establishing this &#8220;patient-like&#8221; orthotopic syngeneic mouse model of HCC metastasis3. The methodology of how to implant BNL 1ME A.7R.1 mouse HCC cells directly into the liver (the organ of origin) of the inbred wild-type immune competent laboratory mouse strain, BALB/c3 using survival surgery will be described. Unlike other mouse xenograft tumor models where human tumor cells are implanted into immune deficient mice, this system is syngeneic and is, therefore, suitable for studying the role of the immune system in tumor metastasis3,5,8. This approach will likely gain widespread use for studying the mechanisms of metastasis in solid organ cancers.

a "patient-like" orthotopic syngeneic mouse model of hepatocellular carcinoma metastasis

The majority of cancer-related deaths are caused by the metastasis of the cancer rather than the primary tumor itself. Yet, the underlying mechanisms of cancer metastasis are still unclear. Animal models are essential for elucidating the mechanisms and for evaluating novel strategies for the treatment of metastatic cancers. Here, an in-depth description of a &#8220;patient-like&#8221; orthotopic syngeneic mouse model for exploring the mechanisms of metastasis of solid organ tumors is provided. The survival surgical implantation of BNL 1ME A.7R.1 mouse hepatocellular carcinoma cells directly into the liver (the organ of origin) of the inbred wild-type immune competent laboratory mouse strain, BALB/c is described. The success and reproducibility of this methodology recommends it for widespread use in elucidating the biological mechanisms of solid organ cancer metastasis.

Os fígados de ratos Balb / c foram implantados com 5 x 10 6 BNL 1ME A.7R.1 células rato HCC. Evidência clínica de desenvolvimento HCC foi observado 63 dias pós-cirurgia. Consequentemente, os ratos foram humanamente eutanasiados. A necropsia foi realizada nos ratos sacrificados. Os pulmões eo fígado foram ressecados e um exame cuidadoso bruta foi realizada para identificar tumores macroscópicos. Em um rato, um tumor superficial foi observada sobre a superfície do fígado com alguma ligação à parede...
