Abstract Transforming growth factor beta (TGF-β) exhibits complex and context-dependent cellular responses. While it mostly induces tumor-suppressive effects in early stages of tumorigenesis, its tumor promoting properties are evident advanced disease. This TGF-β duality is still not fully understood, whether supports invasion metastasis by influencing cancer cells directly, or rather through the stromal compartment remains a matter debate. Here, we utilized library colorectal (CRC) patient-derived tumoroids (PDTs), representing spectrum stages, to study cell-specific responses TGF-β. Using medium conditions allowing for differentiation PDTs, observed induced early-stage tumoroids. PDTs with pathway mutations derived from metastatic tumors were insensitive treatment. Notably, one tumoroid line harboring an atypical KRAS Q22K mutation underwent partial epithelial-to-mesenchymal transition (EMT), associated morphological changes increased invasiveness. On molecular level, this was accompanied elevated expression mesenchymal genes, as well deregulation pathways matrix remodeling cell adhesion. Our results suggest that intrinsic critical determining -promoting effects.
