FC/ICFC analysis with fresh gastric cancer samples (FDU‐ZSH EXPC Arm C) also validated that VISTA+ TAMs exhibited significantly higher expression of M2‐like marker CD163 and CD206, as well as M1‐like marker human leukocyte antigen (HLA)‐DR and CD11c (Figure 4G). Here, CD163 is linked to gastric cancer.
