In addition to VEGF, a recent study of xenograft models has shown that the angiogenesis of TAMs can be induced by pancreatic cancer cells, which secrete IL-35 to recruit TAMs and activate their CXCL1 and CXCL8 to stimulate angiogenesis, and the combination of a neutralizing antibody against IL-35 and gemcitabine significantly decreased monocyte infiltration and microvessel density [108]. This evidence concerns the gene VEGFA and pancreatic neoplasm.
