Project description:Microarray was used to identify differential gene expression pattern in Barrett's esophagus (BE), compared to the normal adjacent epithelia gastric cardia (GC) and normal squamous esophagus (NE) RNA was extraxted from endoscopic biopsies of BE (n=10), GC (n=10) and NE (n=10, only 8 uploaded). One NE sample was excluded since clustered with BE and all the intestinal markers were positive, indicating sampling error.

Project description:Barrett's esophagus is a common type of metaplasia and a precursor of esophageal adenocarcinoma. However, the cell states and lineage connections underlying the origin, maintenance, and progression of Barrett’s esophagus have not been resolved in humans. Here, we performed single-cell lineage tracing and transcriptional profiling of patient cells isolated from metaplastic and healthy tissue. Our analysis unexpectedly revealed that the squamous esophagus and gastric cardia contained cells belonging to common lineages that also included transitional basal progenitor cells; both esophageal and gastric tissues were also related to Barrett's esophagus. Barrett’s esophagus biopsies consisted of multiple clones, with lineages that contained all progenitor and differentiated cell types. In contrast, precancerous dysplastic lesions were initiated by the expansion of a single molecularly aberrant Barrett’s esophagus clone. Together, these findings provide a comprehensive view of the cell dynamics of Barrett's esophagus, linking cell states along the disease trajectory, from its origin to cancer.

Project description:Barrett’s esophagus confers significant risk of esophageal adenocarcinoma. We have established the cloning of patient-matched stem cells of Barrett’s, gastric, and esophageal epithelium. Barrett's esophagus stem cells (BE), gastric cardia stem cells (GC) and normal esophagus stem cells (Eso) from 12 patients were cloned (For BE: 12 patients, GC: 12 patients and Eso: 2 patients). Keratin 5 positive and Keratin 7 positive cells were cloned from human fetal esophageal epithelium. Using air liquid interface culture system, stem cells were induced to differentiate into mature epithelial structures.

Project description:gene expression profiles of Barrett's esophagus, squamous esophagus and gastric cardia
| PRJNA92209 | ENA
Project description:Barrett's esophagus is a metaplastic condition of the distal esophagus, characterized by the replacement of normal squamous epithelium by columnar epithelium. Patients with BE have an increased risk of developing esophageal adenocarcinoma. MicroRNAs have been implicated to be disease and tissue specific, however limited data of microRNA expression in the esophagus is available. Therefore we evaluated microRNA expression profiles of esophageal adenocarcinoma and compared these with Barrett's esophagus and normal squamous esophagus.
