MCA-induced tumor development in WT and CD155-deficient mice.

<p>(A, B) WT (<i>n</i> = 18 and 16, respectively) or CD155-deficient (KO; <i>n</i> = 19 and 20, respectively) C57BL/6N mice were injected s.c. with 5 µg (A) or 100 µg (B) methylcholanthrane (MCA) on day 0. (C) WT (<i>n</i> = 15) or KO (<i>n</i> = 10) BALB/c mice were injected s.c. with 5 µg MCA on day 0. Tumor size in each mouse was measured once a week. Tumor size (top) and survival data (bottom) are shown.
