Transplantation of autologous oral epithelial cell sheets for the prevention of esophageal strictures after endoscopic submucosal dissection[65]. A 55-year-old man underwent esophageal endoscopic submucosal dissection (ESD) for early squamous cell carcinoma. Seven fabricated autologous oral epithelial cell sheets were transplanted immediately after esophageal ESD. At postoperative day 21, the ulcer surface after esophageal ESD was covered with a regenerative mucosa, and no esophageal stricture was present. Figures are reproduced courtesy of Elsevier.
