No differences were observed in the percentage of CD103+ cells in the CD8+-population (CD8+CD103+-cells) between the normal looking squamous epithelium from controls (C SQ 2 cm, C SQ 5 cm), BE patients (BE SQ 5 cm) and normal looking (RE SQ 5 cm) and inflamed epithelium from RE patients (RE) (Figure 4, panels A and B). This evidence concerns the gene CD8A and Barrett esophagus.
