This preclinical murine model of pancreatic cancer metastasis to the liver via a hemispleen injection technique is the first model described that mirrors many of the clinical and immunological conditions of patients with metastatic disease to the liver. This model offers several advantages over other murine models. First, unlike transgenic models of pancreatic cancer in which only 30% of the mice develop metastases to the liver and the timing of metastases formation is quite variable, this model offers the advantage of c...

Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer related deaths in the United States1. The five year survival for patients with metastatic PDA is 2-12%1. Although adjuvant and neoadjuvant chemotherapy for pancreatic cancer is more effective today than ever, there still remains a desperate need for novel therapies.
The development of novel therapeutics necessitates reliable preclinical animal models. Although subcutaneous tumor models are straightforward to use, drawbacks include the inability of these tumors to metastasize and mimic the tumor progression and microenvironments seen in human cancers. Genetically engineered models, such as the genetically engineered mouse containing Kras and p53 knock-in oncogenic mutations (the KPC model)2 and the KPC model with a YFP lineage tracer (the PKCY model)3 allow for the study of naturally occurring tumors in immunocompetent mice. Additionally, the tumor microenvironment is unaltered and more closely resembles that seen in human tumor progression. Unfortunately, the timing of tumor development is variable within these models, which makes it difficult to study experimental therapies. Additionally, backcrossing of these mice requires a significant amount of time and financial commitment, which is not always feasible. Finally, implanted xenograft PDA mouse models necessitate immunocompromised mice, which have altered or absent tumor microenvironments. As a result, the efficacy of experimental therapies demonstrated in these preclinical models are often not reproducible in human clinical trials4.
This hemisplenectomy mouse model utilizes Panc02 tumor cells, which are a highly tumorigenic, methylcholanthrene induced pancreatic tumor cell line derived from C57BL/6 mice5,6. Additionally, other murine PDA cell lines derived from the KPC mice can be used in this model. Schulick et al. have previously developed a hemisplenectomy technique and created a syngeneic mouse model of colon cancer metastases7. This hemisplenectomy model (Figure 1) offers consistent and equal tumor inoculation in immunocompetent mice lending itself to the investigation of novel therapeutic agents7-10.

a preclinical murine model of hepatic metastases

Numerous murine models have been developed to study human cancers and advance the understanding of cancer treatment and development. Here, a preclinical, murine pancreatic tumor model of hepatic metastases via a hemispleen injection of syngeneic murine pancreatic tumor cells is described. This model mimics many of the clinical conditions in patients with metastatic disease to the liver. Mice consistently develop metastases in the liver allowing for investigation of the metastatic process, experimental therapy testing, and tumor immunology research.

Panc02 tumor cells injected into the hemispleen (Figure 1) form liver metastases in 100% of the mice, while lung and peritoneal metastases are not observed if the technique is performed correctly. This technique has been performed on over one hundred mice using Panc02 cells in multiple, independent experiments, and reproducibly, all untreated mice die with liver metastases between 30 and 60 days following the hemisplenectomy procedure (Figure 2). To obtain statistical significance betwee...
