Core Tip
Core tip: As a dominant component in tumor stroma, cancer-associated fibroblasts (CAFs) promote tumorigenesis, and tumor progression by stimulating angiogenesis, malignant cell survival, epithelial-mesenchymal transition (EMT) and proliferation via direct cell-to-cell contact or secretion of soluble factors in most digestive solid tumors. CAFs are characterized by the expression of α-smooth muscle actin, fibroblast activated protein, fibroblast specific protein, vimentin, etc. They are hypothesized to originate from various cells. EMT may also be an important process generating CAFs. A close link exists between CAFs-induced EMT, chemo-resistance of tumor cells, and tumor stem cells. CAFs significantly induce immunosuppression, and may be a prognostic marker. Targeted therapy toward CAFs has displayed promising anticancer efficacy.
