Figure 1
Immunostaining of IL-6 and integrin β6 in CRC samples (magnification, 400x). (a) High expression of IL-6 in the tumor (arrows) as well as stromal cells (arrowheads). (b) Low expression of IL-6. (c) Positive expression of integrin β6 in the tumor cells (arrow in the enlargement). (d) Negative expression of integrin β6. (e) Box-and-whisker plot of IHC score indicates higher immunostaining of integrin β6 in the IL-6-high group than in the IL-6-low group. . IHC: immunohistochemistry.
