Immunohistochemical analysis of Bis in the esophagus (A) and stomach (B-D). Intense Bis immunoreactivity was observed in the stratified squamous epithelium and striated muscles (marked as white or black asterisk, respectively) in the esophagus (A). In epithelia of the grandular stomach, only trace levels of Bis expression were detected (B, C) and weak immunostaining for Bis was detected in the smooth muscles of the stomach, while specific localization of Bis was detected in myenteric plexus (arrows) (B, D). Higher magnifications of the boxed areas in B are shown in C and D. Scale bars=50 µm (A-D).
