Unraveling the role of cancer-associated fibroblasts in colorectal cancer.

Within the intricate milieu of colorectal cancer (CRC) tissues, cancer-associated fibroblasts (CAFs) act as pivotal orchestrators, wielding considerable influence over tumor progression. This review endeavors to dissect the multifaceted functions of CAFs within the realm of CRC, thereby highlighting their indispensability in fostering CRC malignant microenvironment and indicating the development of CAFs-targeted therapeutic interventions. Through a comprehensive synthesis of current knowledge, this review delineates insights into CAFs-mediated modulation of cancer cell proliferation, invasiveness, immune evasion, and neovascularization, elucidating the intricate web of interactions that sustain the pro-tumor metabolism and secretion of multiple factors. Additionally, recognizing the high level of heterogeneity within CAFs is crucial, as they encompass a range of subtypes, including myofibroblastic CAFs, inflammatory CAFs, antigen-presenting CAFs, and vessel-associated CAFs. Innovatively, the symbiotic relationship between CAFs and the intestinal microbiota is explored, shedding light on a novel dimension of CRC pathogenesis. Despite remarkable progress, the orchestrated dynamic functions of CAFs remain incompletely deciphered, underscoring the need for continued research endeavors for therapeutic advancements in CRC management.
