Fig.S4 Clear separation of GFP+ tumor cells and GFP- non-tumor cells.Tumors were harvested at 14 days post-implantation, and a single cell suspension was made. Tumor cells expressing a GFP-luciferase vector were sorted from the suspension. Shown is a representative separation, with clear distinction between viable GFP+ and GFP- cells

Fig.S5Soluble immune mediator expression by tumor-infiltrating stromal cells developed in a fibrotic liver is markedly different from that in a healthy liver. Tumors were harvested at 14 days post-implantation, and a single cell suspension was made. Tumor-infiltrating stromal cells negative for GFP were sorted from the suspension, their RNA extracted and reverse transcribed, and expression of soluble immune mediators examined. Comparison of expression of cytokines in stromal cells isolated from tumors implanted into either olive oil- (red) or carbon tetrachloride- (blue) treated mice, normalized to average expression of these factors in tumor-infiltrating stromal cells implanted into mice which were treated with olive oil.

Table S1 Expression of cytokines in tumor-infiltrating stromal cells isolated from tumors implanted into olive oil- or CCl4-treated mice relative to average level of expression in the olive oil-treated mice. This table contains both summary for treatment groups and raw data for each mouse used in the analysis. Fold changes were generated using the formula:

Fold Change = 2^-(sample Ct value – average of olive oil Ct values)

Table S2Expression of cytokines in tumor cells implanted into olive oil- or CCl4-treated mice relative to expression in the same cell line maintained in culturein vitro. This table contains both summary for treatment groups and raw data for each mouse used in the analysis. Fold changes were generated using the formula:

Fold Change = 2^-(sample Ct value – in vitro Ct value)

Table S3 Expression of cytokines in tumor cells implanted into olive oil- or CCl4-treated mice relative to average expression in the olive oil-treated mice. This table contains both summary for treatment groups and raw data for each mouse used in the analysis. Fold changes were generated using the formula:

Fold Change = 2^-(sample Ct value – average of olive oil Ct values)
