Proangiogenic M2Mφs are reported to secrete several angiogenic factors, such as VEGF, IL-8 (CXCL8), bFGF (basic fibroblast growth factor), TP (thymidine phosphorylase), and MMP (matrix metalloproteinase)11, 36, recolonizing and stabilizing tumour vasculature after irradiation, thereby supporting any remaining viable tumour cells. This evidence concerns the gene FGF2 and neoplasm.
