Compared to adipose stem cell conditioned medium (ADSC-CM), hUCESC-CM contains low levels of factors involved in cancer progression, e.g., EGFR, FGF-4 and -9, intracellular adhesion molecule-3, IL6, IL6R, CCL7, macrophage migration inhibitory factor (MIF), soluble gp130 and VEGF-D [132,133,134,135,136,137,138,139]. This evidence concerns the gene MIF and cancer.
