Fig. 1From: Macrophage-derived exosomal microRNA-501-3p promotes progression of pancreatic ductal adenocarcinoma through the TGFBR3-mediated TGF-β signaling pathwayTumor-associated macrophage recruitment in PDAC associates with cancer metastasis. a and b immunohistochemical staining and quantitative analysis of F4/80 positive expression in metastatic and non-metastatic PDAC tissues. c correlation of TAM recruitment with survival curve of PDAC patients. d relative expression of miR-501-3p in metastatic and non-metastatic PDAC patients. e HE staining for PDAC tissues. * p < 0.05. The measurement data were expressed as mean ± standard deviation. Data between two groups were analyzed by independent sample t test. Kaplan-Meier method and the log-rank test were employed to analyze the relationship between TAM recruitment in PDAC and overall survivalBack to article page
