title: Tumor challenges in immunotoxicity testing.
abstract: Syngeneic murine tumor models have been widely used by researchers to assess changes in tumor susceptibility associated with exposure to toxicants. Two common tumor models used to define host resistance against transplanted tumors in vivo are EL4 mouse lymphoma cells (established from a lymphoma induced in a C57BL/6 mouse by 9,10-dimethyl-1,2-benzanthracene) and B16F10 mouse melanoma cells (derived through variant selection from a B16 melanoma arising spontaneously in C57BL/6 mice). While C57BL/6 mice are commonly used as the syngeneic host for these tumor models, other mouse strains such as B(6)C(3)F(1) (C57BL/6 x C3H) can also be used. Tumor challenge of the host can be done by subcutaneous (sc) or intravenous (iv) injection, depending upon whether the effects are to be examined on local tumor development or experimental/artificial metastasis. Materials and methodologies for injection of both tumor cell models are described in detail in the subsequent sections.
