    摘要: A method of repairing diseased or dysfunctional pancreas or liver is provided. The method involves preparation of a suspension of stem cells and/or progenitor cells such as biliary tree stem cells, hepatic stem cells, pancreatic stem cells or their descendants, committed progenitor cells, from healthy tissue of the patient or of the biliary tree of a non-autologous donor and engrafting the cells into the wall of bile ducts near to the organ to be treated. The graft consists of stem cells or progenitors that are admixed with biomaterials and, optionally, with cytokines and/or native epithelial-mesenchymal cells appropriate for the maturational lineage stage of the cells to be engrafted. The cells are specifically introduced to the hepato-pancreatic common duct of the subject for treatment of pancreatic conditions or to the bile duct wall near to the liver for treatment of liver conditions and allowed to migrate to the pancreas or to the liver and expand and then rebuild part or the entirety of the diseased or dysfunctional organ.

    摘要: The present invention relates to a multipotent stem cell, multipotent cell populations, and an enriched multipotent cell population, each found in fetal, neonatal, pediatric, and adult biliary tree tissue and up to 72 hours post mortem (although preferentially, within 10 hours post mortem) and capable of maturing into multiple endodermal tissues that include liver, biliary and pancreatic tissues. The multipotent stem/progenitor cell and cell populations are found in peribiliary glands, and progenitors descending from them are present throughout the biliary tree including in the gallbladder. High numbers of the peribiliary glands are found in the branching locations of the biliary tree such as hilum, common hepatic duct, cystic duct, common duct, common hepato-pancreatic duct and gallbladder. Related multipotent cells, multipotent cell populations and their descendent progenitors are found throughout the biliary tree including in the gall bladder, which does not have peribiliary glands. Compositions comprising same, methods of identifying and isolating same, maintaining same in culture, expanding same in culture and differentiating or lineage restricting the same in vitro or in vivo to hepatic, biliary or pancreatic fates ( e.g ., as hepatocytes, cholangiocytes, and/or pancreatic islet cells) are also provided. Methods of using the multipotent cells and/or multipotent cell populations are also provided.
