Article Title: Neutrophils Infiltration in the Tongue Squamous Cell Carcinoma and Its Correlation with CEACAM1 Expression on Tumor Cells
doi: 10.1371/journal.pone.0089991
Figure Lengend Snippet: A: There were more CD15+ neutrophils (black arrow) in TSCC tissues (b, c, d) than in peritumoral tissues (a). In tumors areas, some neutrophils lied in the stroma of tumors (b), some were located within the carcinoma nests (c), and some infiltrated in the borderline of tumor invasion (d). (a: 100×; b, c, d: 400×). B: The expression of CEACAM1 in peritumoral tissues was negative or weak (a). In TSCC tissues, CEACAM1 expression was obviously stronger than that in peritumoral tissues and located mainly in the cytoplasm of tumor cells (b). (a: 100×; b: 400×). C: The relationship of CEACAM1 expression on tumor cells and infiltration of neutrophils. In strong CEACAM1 expression tumors, there were more neutrophils (black arrow) (a); While in negative or weak CEACAM1 expression tumors, there were relatively fewer neutrophils (b). (a, b: 200×, for CEACAM1).
Article Snippet: The membrane was blocked with 5% non-fat milk for 1 h, and incubated with monoclonal mouse anti-human CEACAM1 (dilution 1∶500, RD; MAB2244, USA) antibodies for 2 h at room temperature, followed by washing with TBST (TBS containing 0.1% Tween 20) for 5 min five times.
