Effect of high expression of CXCL12 in Cancer-associated fibroblasts on survival of gastric cancer patients. Kaplan-Meier curves showing the impact of CXCL12CAF and overall survival (OS) in 285 gastric cancer (GC) patients, P=0.0107. (B) Kaplan-Meier curves showing the impact of Wnt5a on the OS of patients, P=0.0063. (C) ROC curve showing the performance of the multivariate regression prediction model on patient prognosis, AUC = 0.749. (D) Kaplan-Meier curves showing the impact of CXCL12 on the OS of patients in TCGA-STAD dataset by TIMER tools, P = 0.066. (E) Kaplan-Meier curves showing the impact of CXCR4 on the OS of patients in the TCGA-STAD dataset by TIMER tools, P = 0.001. (F) Schematic diagram of CAFs affecting the progression of GC cells by secreting CXCL12.
