Survival in the Colon26 hepatic metastasis model. 2 × 10⁵ Colon26 cells were injected into the spleen of each mouse on day 0. Colon26-bearing mice were randomly divided into an α-GalCer group and a control Vehicle group (9 mice per group). On day 7, day 14, and every 3 days thereafter, α-GalCer (100 μg/kg body weight) or control Vehicle (same volume as α-GalCer) was inoculated into the peritoneal cavity, and survival was monitored daily until all of the mice had died. ○, Vehicle-treated mice; □, α-GalCer-treated mice.
