Tial of human deciduous pulp stem cell-converted hepatocyte-like cellsRatih Yuniartha1,2, Takayoshi Yamaza3 , Soichiro Sonoda3, Koichiro Yoshimaru1, Toshiharu Matsuura1, Haruyoshi Yamaza4, Yoshinao Oda5, Shouichi Ohga6 and Tomoaki Taguchi1,AbstractBackground: Stem cells from human exfoliated deciduous teeth (SHED) have already been reported to show the in vivo and in vitro hepatic differentiation, SHED-Heps; having said that, the cholangiogenic potency of SHED-Heps remains unclear. Right here, we hypothesized that SHED-Heps contribute to the regeneration of intrahepatic bile duct system in chronic fibrotic liver. Approaches: SHED were induced into SHED-Heps below cytokine stimulation. SHED-Heps had been intrasplenically transplanted into chronically CCl4-treated liver fibrosis model mice, followed by the analysis of donor integration and hepatobiliary metabolism in vivo. Immunohistochemical assay was examined for the regeneration of intrahepatic bile duct program in the recipient liver. Furthermore, SHED-Heps had been induced below the stimulation of tumor necrosis element alpha (TNFA). Results: The intrasplenic transplantation of SHED-Heps into CCl4-treated mice showed that donor SHED-Heps behaved as human hepatocyte paraffin 1- and human albumin-expressing hepatocyte-like cells in situ and ameliorated CCl4-induced liver fibrosis. Of interest, the integrated SHED-Heps not simply expressed biliary canaliculi ATP-binding cassette transporters such as ABCB1, ABCB11, and ABCC2, but additionally recruited human keratin 19(KRT19-) and KRT17-positive cells, which are deemed donor-derived cholangiocytes, regenerating the intrahepatic bile duct program inside the recipient liver. In addition, the stimulation of TNFA induced SHED-Heps into KRT7- and SRY-box 9-positive cells. Conclusions: Collectively, our findings demonstrate that infused SHED-Heps showed cholangiogenic capability under the stimulation of TNFA in CCl4-damaged livers, resulting in the regeneration of biliary canaliculi and interlobular bile ducts in chronic fibrotic liver. Thus, the present findings suggest that SHED-Heps may be a novel supply for the treatment of cholangiopathy.
