Specifically, TCM contained soluble factors responsible for the recruitment and adhesion of myeloid cells to the tumor including macrophage inflammatory protein-1β (MIP-1β), vascular endothelial growth factor-α (VEGF-α), IL-8, IFN- γ, and granulocyte colony-stimulating factor (G-CSF) [14, 15]. This evidence concerns the gene CXCL8 and neoplasm.
