Tumor-infiltrating Monocytic Myeloid-derived suppressor cells play a key role in forming immunosuppressive microenvironment in  human gastric cancer
The present data suggest that M-MDSC, play a predominant role in forming the immunosuppressive microenvironment in GC. Overall design: We performed scRNA-seq analysis from 17 gastric cancers, 8 esophageal squamous cell carcinoma, 10 normal gastric mucosae, and 5 normal esophageal mucosae.
