Characterization of CAF subtypes in murine PDAC. (A) UMAP plot showing various CAF subtypes identified in PDAC tumors from KPC mice. (B) Expression of commonly used CAF markers in KPC-derived PDAC CAFs. (C) Dot plot showing the expression of selected markers of Ly6c1high CAFs (iCAFs) and α-SMAhigh CAFs (myCAFs) in KPC-derived PDAC CAFs. Dot size represents the fraction of cells expressing a specific marker in a particular cluster and intensity of color indicates the average expression in that cluster. (D) Violin plots showing the expression of Cd74high CAF (apCAFs) markers in KPC-derived CAFs (cluster identities on X-axis). (E) CAF subtypes identified in subcutaneous mT3 tumors. (F) Expression of commonly used CAF markers in mT3 tumor-derived CAFs. (G) Dot plot showing the expression of selected iCAF and myCAF markers in mT3-derived CAFs.
