Analysis of immune cell accumulation in tumor tissues and levels of IL-1β. a–c Tumor tissue was excised and fixed in 3 dpi, cryo-sectioned, and immunostained for IL-1β plus CD68 (macrophages), Ly-6G/ls), or CD11c (dendritic cells). Representative images from three independent experiments are shown. d Flow cytometry analysis was used to examine levels of IL-1β in each group in the tumor-draining spleen
