Lack of CD4+ T cells in sh C/EBPβ tumor-bearing mice attenuates the effect of C/EBPβ on tumor growth and metastasis formation. (a) 4T1 tumor growth (non-treated sh C/EBPβ, anti-CD3-treated sh C/EBPβ, anti-CD4-treated sh C/EBPβ) in BALB/c mice (n=8 mice per group). (b) Number of CTCs in the blood (left panel) and bone marrow (right panel) of tumor-bearing mice. (c) Tumor volume in nude mice 14 days after implantation (left panel) and percentage of nude tumor-bearing mice developing lung metastasis (right panel). (d) Human breast cancer tissue stained for MHCII (DAB) and C/EBPβ (Alexa 594).
