| 3 | Hepato-biliary profile of potential candidate liver progenitor cells from healthy rat liver显示文摘AIM:To evaluate the presence of progenitor cells in healthy adult rat liver displaying the equivalent advanced hepatogenic profile as that obtained in humans.METHODS:Rat fibroblastic-like liver derived cells (rFLDC) were obtained from collagenase-isolated liver cell suspensions and characterized and their phenotype profile determined using flow cytometry,immunocytochemistry,reverse transcription polymerase chain reaction and functional assays.RESULTS:rFLDC exhibit fibroblastoid morphology,express mesenchymal (CD73,CD90,vimentin,-smooth muscle actin),hepatocyte (UGT1A1,CK8) and biliary (CK19) markers.Moreover,these cells are able to store glycogen,and have glucose 6 phosphatase activity,but not UGT1A1 activity.Under the hepatogenic differentiation protocol,rFLDC display an up-regulation of hepatocyte markers expression (albumin,tryptophan 2,3-dioxygenase,G6Pase) correlated to a down-regulation of the expression of the biliary marker CK19.CONCLUSION:Advanced hepatic features observed in human liver progenitor cells could not be demonstrated in rFLDC.However,we demonstrated the presence of an original rodent hepato-biliary cell type. | Cédric Maerckx Isabelle Scheers Tatiana Tondreau David Campard Omar Nyabi Mustapha Najimi Etienne Sokal | 2012 | World Journal of Gastroenterology2012，18，27： | 1 |
