Figure 2. FMD in combination with doxorubicin (DXR) promotes accumulation of tumor-infiltrating lymphocytes (TILs) in the tumor bed.
(A) Bone marrow collected from BALB/c mice undergoing FMD/DXR treatments (see Figure S3A) was collected at the end of the experiment and analyzed with FACS (n=6) to assess the amount of Common Lymphoid Progenitors (CLP). (B) Breast cancer (4T1) tumor tissues collected at the end of the experiment (see Figure S3A) were analyzed using immunohistochemistry to assess CD3+/CD8+ TILs (n=8) (quantification on the right). (C, E) CD3+/CD8+ and (D, E) CD3+/CD4+/CD25+were also assessed by FACS analysis (n=7) in tumor tissue collected from a separate, equivalent experiment (see Figure 1C). (F) Melanoma (B16) tissue collected (see Figure 1E) was also processed to assess the levels of TILs (quantification on the right). Bar scale for DAPI, CD3 and CD8 is 75 μm. Bar scale for CD3+/CD8+ is 12.5 μm Data represented as mean ± SEM. The significance of the differences between experimental groups was determined by using one-way ANOVA (Tukey post-analysis test). p-values <0.05, 0.01 and 0.001 are indicated as *, **, and ***, respectively.
