One of the difficulties in studying ovarian cancer historically has been the lack of a suitable animal model that replicates the human disease. Mouse models that utilize intraperitoneal implantation of tumorigenic cells lack interaction between the transformed ovarian epithelial cells and the ovarian stroma, which we have shown to be an integral component in replicating the etiology seen in human epithelial ovarian cancer (Greenaway, Gynecol Oncol 108:385-394, 2008). Xenograft models generally require the use of immunocompromised hosts, which then eliminates the influence of the immune system in disease progression, which also has been shown to be an important part of the progression of epithelial ovarian cancer (EOC). In this chapter, we describe the generation and optimization of an orthotopic, syngeneic mouse model and illustrate the importance of facilitating epithelial-stromal cell interaction to more closely replicate human EOC.
