Figure 2A presents the relative mRNA expression of several growth factors such as FGF-2, TGF-β1 and VEGF-A as well as EMT markers (E-cadherin, Snail, Slug, Vimentin, α-SMA and fibronectin) in tumoral tissues of SRCA as compared to the peripheral region of tumor. This evidence concerns the gene SNAI2 and neoplasm.
