Figure Lengend Snippet: a In vivo bioluminescence of flux emitted by LL/2-Luc2 carcinoma (LLC) cells in tumor bearing femur after vehicle or DMXAA treatment (2 × 20 mg/kg, i.p.) measured at d8, d11, and d15 post tumor inoculation ( n = 10 vehicle-treated mice, n = 11 DMXAA-treated mice). Images (left) were obtained at 15 min after i.p. injection of D-luciferin (30 mg/kg). Right, experimental scheme and quantification of a . b Ratio of maximum thigh circumference reflecting local tumor burden in mice with each indicated treatment on d17 after LLC implantation. Left, vehicle or DMXAA treatment (2 × 20 mg/kg, i.p.; n = 11 vehicle-treated mice and n = 9 DMXAA-treated mice). Right, vehicle, ADU-S100 (2 × 20 mg/kg, i.p.) or ZA (zoledronic acid; 2 × 100 µg/kg, i.p.) treatment ( n = 8 vehicle-treated mice and n = 7 ADU-S100-treated mice, and n = 8 ZA-treated mice), *** P < 0.001. c Ratio of maximum thigh circumference in mice administered with vehicle, DMXAA or ADU-S100 (2 × 100 µg/kg, i.p.) on d17 after implantation of E0771 breast cancer cells ( n = 7 mice/group), *** P < 0.001. d Images of lung tumor nodules in mice with each indicated treatment on d17 after LLC inoculation. Left, representative dorsal and ventral murine lung image, with arrows showing metastatic tumor nodules. Right, H&E staining for sections from lung samples in Left. Arrows indicates the areas with tumor cells, scale bar, 2 mm. 1 and 2 are enlarged images showing tumor tissue and peritumoral areas, respectively. Scale bar, 50 µm. Note that tumor cells have large and irregular nuclei with loss of the normal alveolar structure. e Quantification of panel d ( n = 8 vehicle-treated mice, n = 7 ADU-S100-treated mice, and n = 8 ZA-treated mice). f - g FACS analysis of CD4 + and CD8 + T cells ( f ) or Treg cells ( g ) within the bone marrow tumor microenvironment in mice treated with vehicle or DMXAA (2 × 20 mg/kg, i.p.) on d8 post-LLC inoculation ( n = 5 mice/group). The gating strategy for this figure is provided in Supplementary Fig. 7. h Local tumor burden as determined by the ratio of maximum thigh circumference after vehicle or DMXAA treatment in WT ( n = 10 mice for vehicle or DMXAA group) and Rag1 −/− mice ( n = 13 mice for vehicle or DMXAA group) on d17 after LLC implantation, *** P < 0.001. i Local tumor burden as determined by the ratio of maximum thigh circumference in Batf3 +/+ and Batf3 −/− mice with indicated treatment measured on d17 after LLC implantation ( n = 8 mice/group), *** P < 0.001. Data indicate the mean ± SEM, repeated-measures two-way ANOVA with Bonferroni’s post hoc test ( a , b , c , h , i ); one-way ANOVA with Bonferroni’s post hoc test ( e ); two-tailed Student’s t -test ( f , g ).
