Impact of injection of OK-432-stimulated DCs into murine MC38 subcutaneous tumors. a RFA was administered to a tumor on one flank followed by injection of 1 × 107 DCs into the treated tumor. The untreated tumor on the opposite flank was observed for 10 days. The solid arrowheads indicate the treatment intervention sites, and the open arrowhead indicates the observed untreated tumor. b The tumor volumes were compared among the four groups as follows: (1) no treatment; (2) RFA only; (3) RFA in combination with immature DC injection; and (4) RFA in combination with OK-432-stimulated DC injection. n = 8 mice per group. The data are presented as the mean ± SE. *P < 0.05; **P < 0.001
