When the cytokine composition of the supernatant of a 48 h culture of digested Pan02 tumors, referred to as “tumor-conditioned media” (TCM), was assessed, we previously inferred that IL-6 levels were higher in TCM from mice treated with the TGFβ vaccine than in TCM from control-vaccinated mice [11]. This evidence concerns the gene TGFB1 and neoplasm.
