Fig. 6From: CD4+CCR8+ Tregs in ovarian cancer: a potential effector Tregs for immune regulationIn vitro chemotaxis experiment of CD4+CCR8−/CCR8+ Tregs A Comparative analysis of the difference of chemotactic ability of CD4+CCR8+ Tregs in the medium containing gradient concentration CCL1/CCL18. B Comparative analysis of the difference of response chemotaxis between CD4+CCR8− Tregs and CD4+CCR8+ Tregs. Each experiment was performed triplicated. Data are presented as means ± SD and analysed with the non-parametric Mann–Whitney U test. (*P < 0.05)Back to article page
