text: [Carcinoma-associated fibroblasts in cancer: the great escape].
  Cellular and molecular crosstalks between cancer and non-cancer tumor-associated cells result in tumor growth and metastatic spreading. During carcinoma development, tumor cells secrete signaling molecules that influence the surrounding non-cancer cells, which, in return, favor tumor cell growth, survival, migration and metastasis. Carcinoma-associated fibroblasts (CAF) are the most abundant population of non-cancer cells found in tumors, and their presence is often associated with poor clinical prognosis. Here, we summarize the pro-carcinogenic roles of CAF cells during carcinogenesis, with a specific focus on their abilities to drive cancer cell-dependent pro-invasive extracellular matrix remodeling.
