| Outline of Final Research Achievements |
During liver development, liver progenitor cells (LPCs) differentiate into mature hepatocytes through interactions with hepatic non-parenchymal cells (NPCs) such as liver sinusoidal endothelial cells (LSECs) and hepatic stellate cells (HSCs). In this study, to induce functional hepatocytes from hiPSCs, we established a co-culture system of LPCs and NPCs. We show that TGFb and Rho signaling pathways, respectively, regulate the proliferation and maturation of LSECs and HSCs isolated from mouse fetal livers. Based on the results in mice, we established the hiPSC-derived LSECs and HSCs. They could support proliferation and maturation of hiPSC-derived LPCs by expressing numerous hepatic mitogens and extracellular matrix proteins.
