However, the heterogeneity, plasticity, and functional roles of CAFs in CRC remain poorly understood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We integrated single\u2010cell RNA sequencing (scRNA\u2010seq) data from four public CRC datasets and spatial transcriptomics data. Using computational approaches such as Harmony, Monocle2, and CellChat algorithms, we analyzed cellular landscapes, CAF subtype identification, developmental trajectories, transcription factor networks, and cell\u2013cell communications to reveal CAF heterogeneity and their crosstalk with other cell subtypes in CRC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified eight distinct CAF subtypes with unique gene expression profiles and developmental plasticity. The CTHRC1+ CAF subtype was significantly associated with T cell exclusion and upregulated expression of immune checkpoint genes. We uncovered a specific communication axis between CTHRC1+ CAFs and MMP7+ malignant epithelial (Malig\u2010Epi) cells mediated by the thrombospondin (THBS)2\u2010SDC4 ligand\u2013receptor signaling. High infiltration of both cell types synergistically correlates with worse prognosis and unfavorable response to immunotherapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our study delineates CAF heterogeneity in CRC and highlights the CTHRC1+ CAF subtype as a critical organizer of an immunosuppressive niche.
