Representative immunohistochemical staining pattern of ANXA1 expression in gastric and colon cancer. Immunohistochemical analysis of ANXA1 expression in gastric cancer (A–E) and colon cancer (F–J). (A) Strongly positive staining, ≥25% of tumor cells. (B) Moderately positive staining, 15–25% of tumor cells. (C) Weakly positive staining, 5–15% of tumor cells. (D) Negative staining, <5% of tumor cells. (E) Normal gastric mucosa. (F) Strongly positive staining, ≥25% of tumor cells. (G) Moderately positive staining, 15–25% of tumor cells. (H) Weakly positive staining, 5–15% of tumor cells. (I) Negative staining, <5% of tumor cells. (J) Normal colon mucosa. Magnification, x40.
