Survival curves for three groups. The ex vivo, in vivo, and splenectomy groups significantly differed in survival (P = 0.018, log-rank test). This difference was especially pronounced between the ex situ and splenectomy groups (P = 0.005, P < 0.017). In the pairwise comparisons, Bonferroni modification was carried out. P < 0.017 (two-sided) was considered significant
