Cxcl2, Ccl2, Ccl3, and Ccl8 can act as chemoattractants for myeloid cell recruitment in tumors [46], while Csf1, Csf2, and Csf3 are central to controlling the recruitment, proliferation, and differentiation of immunosuppressive myeloid cells [46], including macrophages and neutrophils in the tumor. Here, CCL8 is linked to neoplasm.
