Analysis of a single-cell RNA sequencing dataset that included 26 primary gastric tumors (GSE183904) showed that six of the genes (IGFBP7, CALD1, TAGLN, TUBB6, LAMC1, and RAI14) were expressed mainly in cancer-associated fibroblasts (CAFs) and endothelial cells (Supplementary Figure S12), while ITGB5, MXRA7, ACTA2, and TPM2 were expressed primarily in CAFs (Supplementary Figure S12). Here, ITGB5 is linked to cancer.
