Inflammatory cells are recruited by tumours and play a supporting role during tumour progression, promoting tumour expansion by stimulating angiogenesis and arteriogenesis, and tumour metastasis through lymphangiogenesis. bFGF, basic fibroblast growth factor; CSF, colony-stimulating factor; MCP, macrophage chemoattractant protein; MMP, matrix metalloprotease; TGF, transforming growth factor; TNF, tumour necrosis factor; VEGF, vascular endothelial growth factor.
