［Abstract］ Gastric cancer is closely related to the reprogramming of the tumor microenvironment，but the complexity and
heterogeneity of the tumor microenvironment presents a significant challenge to the development of individualized and precise diagnose
and treatment strategies for gastric cancer. Focusing on the reprogramming process of tumor microenvironment，single⁃cell sequencing
technology can depict the“landscape”of the gastric cancer tumor microenvironment at the single⁃cell level，explore the interactions
between cell subtypes and their components，reveal the novel immune mechanisms by which the tumor microenvironment regulates the
progression and metastasis of gastric cancer，explore the molecular mechanism of chemo⁃resistance in the tumor microenvironment of
gastric cancer，identify the potential immunotherapy targets for gastric cancer within the tumor microenvironment，and provide a new
prediction method for the prognosis of gastric cancer. The technology will provide more comprehensive and precise evidence for the
study of origin，pathogenesis，progression，and immune tolerance in gastric cancer. The following paper reviews the application of single⁃
cell RNA sequencing technology in the reprogramming of the tumor microenvironment in gastric cancer and attempts to provide new
ideas for the precise diagnosis and treatment of gastric cancer.
