肿瘤相关成纤维细胞( Cancer-associated-fibroblasts,CAFs)是肿瘤外部微环境中最重要的细胞成分之一.CAFs可以与肿瘤细胞发生相互作用,分泌多种可溶性因子如生长因子、趋化因子等,并通过调控大肠癌进展过程中发挥关键作用的多条信号通路,参与大肠癌的增殖、侵袭、转移以及耐药等生物学过程.近年研究发现,CAFs相关标记物及基因可作为大肠癌患者预后判断的参考指标,因此,靶向CAFs有望成为大肠癌早期诊断、治疗以及预后判断的关键靶点.本文主要就CAFs的特征、募集与活化过程以及在大肠癌发生发展中的作用进行总结,以期为CAFs在大肠癌中作用机制研究及临床应用提供新的科研方向.%Cancer-associated fibroblasts(CAFs)are one of the most important cellular components in the external microen-vironment of tumors. CAFs can interact with tumor cells and secrete a variety of soluble factors such as growth factors,chemokines,and so on. CAFs are also involved in the proliferation,invasion,migration,metastasis and drug resistance of colorectal cancer through regu-lating multiple signaling pathways that play a key role in the progression of colorectal cancer. Recent studies have found that CAFs re-lated markers and genes can be used as reference indicators for the predicting prognosis of colorectal cancer. Therefore,targeting CAFs may be a key target for early diagnosis,treatment and prognosis of colorectal cancer. This article summarizes the characteristics of CAFs,recruitment and activation process,and its role in the development of colorectal cancer in order to provide a new scientific di-rection for the mechanism of action and clinical application of CAFs in colorectal cancer.
