Our findings revealed higher levels of PDGF-C gene expression than other angiogenic factors, including ANGPD-1, ANGPD-2, ANGPD-3, ANGPD-4, PDGF-A, PDGF-R, PDGF-D, EGF, FST, VEGF-A, VEGF-C, and TGF in visfatin-treated chondrosarcoma cells (Figure 2a). This evidence concerns the gene FST and chondrosarcoma.
