Abstract

Cancer-associated fibroblasts (CAFs) display significant functional and molecular heterogeneity within the tumor microenvironment, playing diverse roles in Cancer progression. Employing single-cell RNA Sequencing data of colorectal Cancer (CRC), we identified a subset of matrix CAFs (mCAFs) as a critical subtype that secretes THBS2, a molecule linked to advanced Cancer stages and poor prognosis. Spatial transcriptomics and multiplex immunohistochemistry revealed clear spatial colocalization between THBS2-producing mCAFs and tumor cells. Mechanically, CAF-secreted THBS2 binds to CD47 on tumor cells, triggering the MAPK/ERK5 signaling pathway, which enhances tumor progression. The tumor-promoting role of THBS2 was further validated using fibroblast-specific THBS2 knockout mice, patient-derived organoids, and xenografts. Moreover, the transcription factor CREB3L1 was identified as a regulator of the transformation of normal fibroblasts into THBS2-producing mCAFs. These findings underscore the pivotal role of THBS2 in CRC progression and highlight the therapeutic potential of targeting the THBS2-CD47 axis and CREB3L1 in CRC.
