Functional tumor vascularization is enhanced by omental adipose-derived MSCs via the upregulation of vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), and stromal cell-derived factor 1-α (SDF1-α), thus resulting in increased cancer cell survival during the formation of the metastatic microenvironment [65]. Here, CXCL12 is linked to cancer.
