TGFB1 and neoplasm: Most of the identified proteins, including fibulin‐5 (FBLN5), solute carrier family 2 facilitated glucose transporter member 1 (SLC2A1) and cell surface glycoprotein MUC18, were more abundant in TGF‐β‐induced fibroblasts, indicating the presence of myofibroblast‐like CAFs in peripheral tumor regions.121 For hepatocellular carcinomas, reference profiles were generated from cultured patient‐derived cancer cells and CAFs.
