doi: 10.1002/jbt.71127
Figure Lengend Snippet: TAMCs recruit Tregs into the tumor microenvironment by secreting chemokines. (A) ELISA detection of CCL1, CCL5, CCL17, CCL22, and CCL28 secretion by TAMCs (after subtracting CCL1, CCL5, CCL17, CCL22, and CCL28 levels in TCCS); (B) ELISA detection of CCL17 levels in tumor tissues and adjacent tissues; (C) Correlation analysis between TAMCs and CCL17 concentration; D: Correlation analysis between Tregs and CCL17 concentration; (E, F) Transwell migration assay to assess Treg migration capacity. Data are presented as mean ± SD. (A, B), independent samples t ‐tests ( N = 3); (C, D) Spearman 's rank correlation analysis ( n = 59); (F), one‐way ANOVA and Tukey's multiple comparison test ( N = 3). * indicates p < 0.05, ** indicates p < 0.01, *** indicates p < 0.001.
