Furthermore, other chemokines such as CCL1, CCL2, CCL3, CCL11, CCL15, CCL16, CCL23, and CX3CL1 have also been implicated in tumor neovascularization by promoting migration and differentiation with or without the proliferation of endothelial cells and inducing new blood vessel formation [113,114,115,116,117,118,119,120]. The gene discussed is CCL2; the disease is neoplasm.
