Cell cloning of Barrett's esophagus stem cell, gastric cardia stem cells and normal esophagus stem cells

Barretts esophagus confers significant risk of esophageal adenocarcinoma. We have established the cloning of patient-matched stem cells of Barretts, 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.
