Our results show that a marked correlation between the CD103+DC signature (IRF8, FMS‐like tyrosine kinase 3 ligand, CLEC9A, CLNK, XCR1, BATF3, and ZBTB46) and chemokines C‐X‐C motif chemokine ligand 9, CXCL10, and CD8A in a mouse model with DMBA/TPA‐induced skin cancer. This evidence concerns the gene CD8A and skin cancer.
