| Research Abstract |
Human hepatocytes are useful for pharmacokinetic examinations. However, considerable donor-dependent variations are problematic. The small intestine, as well as liver, plays an important role in all aspects of pharmacokinetics. At present, human intestinal epithelial cells are difficult to obtain, and there is no appreciate model cells. Instead, other tissue cell-derived cell lines, including Caco-2 cells and MDCK cells, were used as intestinal model in a drug absorption study. Human iPS cells apparently differentiate into various types of mature cells, and are thereby an attractive source for routine access to large numbers of cells that can be used for the pharmacokinetic examinations replacing primary cells. In this study, we investigated the effects of small-molecule compounds for differentiation of human iPS cells into hepatocytes and enterocytes available in pharmacokinetic study.
