Abstract: A sheet-shaped cell culture for covering a cut surface of a pancreas, the cut surface of the pancreas includes cut surfaces of a pancreatic parenchyma and a pancreatic duct, and is connected to an intestinal wall of a small intestine in a liquid-tight manner via the sheet-shaped cell culture. A method for preventing or treating pancreatic fistula includes a step of covering, using a sheet-shaped cell culture, a cut surface of a pancreas that includes cut surfaces of a pancreatic parenchyma and a pancreatic duct, and a step of connecting the cut surface of the pancreas to an intestinal wall of a small intestine in a liquid-tight manner via the sheet-shaped cell culture.

Abstract: A bioadhesive sheet-shaped material configured to be attached onto a surface of an organ, a method for producing the bioadhesive sheet-shaped material, and a method for treating a disease by using the bioadhesive sheet-shaped material. The bioadhesive sheet-shaped material includes an extracellular matrix layer, a sheet-shaped cell culture, and a biodegradable gel layer, where the sheet-shaped cell culture is interposed between the extracellular matrix layer and the biodegradable gel layer, and the bioadhesive sheet-shaped material is by attaching the extracellular matrix layer onto a surface of an organ.

Abstract: A device for efficiently attaching a sheet-shaped object to a target site includes a support body for supporting a sheet-shaped object, and a protective member having a low coefficient of friction for protecting one surface of the support, in which the support body supporting the sheet-shaped object is rolled while being protected by the protective member and can be inserted into a tubular body.

Abstract: Disclosed are embodiments of a sheet-shaped cell culture for promoting healing of a lumen organ having a damaged part, particularly tissue of a duodenum, a method for producing a sheet-shaped cell culture. Also disclosed are embodiments of a method for regenerating a damaged part in a lumen organ using a sheet-shaped cell culture described herein.

Abstract: The present invention addresses the problem of providing a cell sheet composition for healing or preventing discharge from a wounded region of a luminal organ. The present invention also addresses the problem of providing a method in which the cell sheet composition is affixed to a wounded region of a luminal organ to heal or prevent discharge from the wounded region of the luminal organ. The present invention provides a cell sheet composition including mesenchymal stem cells which is characterized by being affixed to a wounded region of a luminal organ in order to heal or prevent discharge from the wounded region of the luminal organ. The present invention also provides a method in which the cell sheet composition including mesenchymal stem cells is affixed to a wounded region of a luminal organ to heal or prevent discharge from the wounded region of the luminal organ.
