Based on the previous literature,34, 35 cluster 12 was divided further into myofibroblastic cancer‐associated fibroblast (CAF) (TAGLN, MYL9, MMP11, and POSTN), inflammatory CAF (CXCL2, PDGFRA, CXCL12, and DPT), antigen‐presenting CAF (HLA‐DRA and HLA‐DRB1) and unidentified CAF (Figure 4E–G), and the overall expression of the 12 genes was analyzed (Figure 4D). Here, TAGLN is linked to cancer.
