Studies have shown that MCs accumulate in tumors and their microenvironment, inferring potential for influencing tumor development, tumor-induced angiogenesis, tissue remodeling, and shaping of adaptive immune responses to tumors by release of certain subsets of mediators (e.g., EGF, NGF, PDGF, SCF, angiopoetin, heparin, IL-8, VEGF). Here, NGF is linked to neoplasm.
