Among these chemokines, CCL2 was shown to be correlated to residual tumor progression.[14] In our study, we found CCL2 and CCL7, known as immunosuppression‐related chemokines, to be dominantly expressed in macrophages, which was confirmed by IF (Figure 2E,F).[25, 26] We searched the TCGA gene expression for chemokines indicative of progression‐free survival in HCC. Here, CCL7 is linked to hepatocellular carcinoma.
