FIG. 6.
Melanoma colony formation in mouse peritoneal cavity. Female C57BL/6 mice were intraperitoneally injected with 3.5×105 B16 cell suspensions containing indicated ODN (25 μg per mouse) or PBS. All mice were sacrificed 7 days later. (A) Representative melanoma colony formation in the peritoneal cavity of mice in each group was indicated. Open arrows indicate the melanoma colonies. (B) The melanoma colony numbers in the peritoneal cavity of mice. Each number is represented by an open circle (n=4–5).The geometric mean of each group is indicated by a horizontal bar. Statistical significance was determined using the nonparametric test; p values are shown between each group.
