Figure 4 Representative results of immunohistochemical analysis of COX-2 in squamous carcinoma tissues and matched normal tissues of the esophagus from the same patient (Magnification x200). In normal esophageal tissue there is no positive staining for COX-2 (A) but in esophageal squamous cell carcinoma tissue, carcinoma cells display a strong staining for COX-2, which indicate COX-2 expression specifically in cancer tissues (B).
