Figure 2

Tumor weights in normal and chimeric mice at day 18 following intradermal inoculation with 1 × 10 ⁶ B16-F0 tumor cells. Each group includes 5 mice. The B/W coat chimera group includes mice # 1–5 from Table 1 and the White coat chimera group includes mice # 7–11 from Table 1. Error bars represent standard deviations of samples from individual mice. Differences in tumor weight of the B/W coat chimera group and the W coat chimera group with respect to the C57 × FVB F1 control group are highly significant (p < 0.001 for both sets).
