Single cell RNA-seq reveals profound transcriptional similarity between Barrett’s oesophagus and oesophageal submucosal glands

Abstract

Barrett’s oesophagus is associated with an increased risk of oseophageal cancer, but its cell of origin is unclear. Here the authors show, using single-cell RNA sequencing of biopsies from six patients and two unaffected subjects, that cells in Barrett’s oesophagus show a transcriptional profile that is similar to that of cells in oesophageal submucosal glands.
