The representative markers used were as follows: IGF1 and C7 for normal fibroblasts (NFs), MYH11 and RGS5 for smooth muscle cells/pericytes, CXCL8 and APOE for inflammatory cancer-associated fibroblasts (iCAFs), HLA-DPA1 and CD74 for antigen-presenting cancer-associated fibroblasts (apCAFs), and COL3A1 and FN1 for myofibroblastic cancer-associated fibroblasts (myCAFs). Here, COL3A1 is linked to cancer.
