MMP9 and neoplasm: Myeloid‐associated (M‐CSF, GM‐CSF, and MIF) or fibroblast growth factor (FGF‐2, FGF‐7), vascularization (VEGF‐C, VCAM‐1), or extra‐cellular matrix components (MMP‐1, MMP‐9, and collagen, type 1 alpha 1) were little or unaffected by vaccination, suggesting tumor regression driven by Th1 inflammation without other global modifications of the TME (Hong et al, 2022).
