IL-10 expression supports EMT in invasive LSCC. (a) IL-10 plasmatic concentrations by ELISA in healthy donors (HD) (n = 9) and LSCC patients (n = 20), and Mann–Whitney U test performed for statistical analysis; data are shown as mean ± SD, . (b) Representative IL-10 and CD68 stainings in laryngeal tissues (magnification ×40) (yellow arrow: normal epithelium, black arrow: tumor cells, and green arrow: stomal cells). (c) Percentage of stromal cells producing IL-10 was evaluated by IHC and correlated to the percentage of CD68 + stromal macrophage by the Pearson correlation test. (d) Correlogram: EMT biomarkers expression levels versus IL-10 and NOS2 expression in invasive LSCC (n = 20).
