DNA Damage in CD133-Positive Cells in Barrett’s Esophagus and Esophageal Adenocarcinoma

Figure 1

CD133 expression in normal esophageal (Normal), Barrett’s esophagus (BE), and Barrett’s adenocarcinoma (BEA) tissues. CD133 expression (red) was examined by immunofluorescence technique. DAPI (blue) was used for nucleic counterstaining. The original magnification is ×200 (a). (b) represent enlarged pictures of the yellow boxes in (a). Arrowheads indicate CD133 expression at apical surface. Arrows indicate cell membrane and cytoplasmic CD133 staining.
