Tumor-infiltrating effector cells of α-galactosylceramide-induced antitumor immunity in metastatic liver tumor

Table 1 Liver weight and number of metastatic nodules.

Liver Weight (g)	1.55 ± 0.21*	1.39 ± 0.14	1.23 ± 0.02*	1.25 ± 0.03
Number of Metastatic Nodules	17.6 ± 9.2**	8.3 ± 5.8**	-	-

2 × 10⁵ colon26 cells were inoculated to spleens. On days 7, 14, 17, and 20, 100 μg/kg body weight of α-GalCer or an equal amount of vehicle was injected intraperitoneally into mice. On day 21, mice were sacrificed and liver weight was measured individually. Livers from sham operated mice without tumor inoculation were also measured as control. Metastatic nodules exposing liver surface were counted. *,**: p < 0.05.
