On the other hand, umbilical cord (UCD)-MSC-CM contains low levels of factors which promote tumor growth (epidermal growth factor receptor (EGFR), FGF-4 and -9), neo-angiogenesis (VEGF, IL-6, IL6 receptor), homing of naïve T cells to peripheral lymph nodes (chemokine (C-C motif) ligand 7 (CCL7)) and migration of circulating monocytes in tumor tissue (macrophage migration inhibitory factor (MMIF)) [37]. This evidence concerns the gene VEGFA and neoplasm.
