The OncoMouse or Harvard mouse is a type of laboratory mouse (Mus musculus) that has been genetically modified using modifications designed by Philip Leder and Timothy A Stewart of Harvard University to carry a specific gene called an activated oncogene (v-Ha-ras under the control of the mouse mammary tumor virus promoter). The activated oncogene significantly increases the mouse's susceptibility to cancer, and thus makes the mouse a suitable model for cancer research.

frameless|right frameless|right BALB/c is an albino, laboratory-bred strain of the house mouse from which a number of common substrains are derived. Now over 200 generations from New York in 1920, BALB/c mice are distributed globally, and are among the most widely used inbred strains used in animal experimentation.
