Cancer-associated fibroblasts (CAF) are essential for cancer hallmarks. While CAFs are molecularly heterogeneous, a CXCL14-expressing subset has been a critical player in the cancer context. In breast cancer, an autocrine fibroblast CXCL14/ACKR2 axis mediates epithelial-to-mesenchymal transition and endows metastatic traits, which offers novel therapeutic potential in the clinical setting.See related article by Sjöberg et al., p. 3702.
