CXCL8 and breast cancer: Endothelial cell recruitment relies on TAM-derived products, including vascular endothelial growth factor A (VEGFA), VEGF receptor 2, adrenomedullin, angiopoietin 2, C-X-C motif chemokine ligand 8 (CXCL8), and CXCL12 (28, 33, 34), which, respectively, were observed both in vitro and in vivo in human and breast cancer models in mouse (35).
