Outline of Final Research Achievements |
In this study, we aimed to establish an efficient differentiation method for highly functioning hepatocyte-like cells from human ES/iPS cells. First, we attempted to improve the hepatocyte differentiation method. Next, we developed a method to concentrate the highly functioning hepatocyte-like cells. The hepatic functions of human ES/iPS cell-derived hepatocyte-like cells were enhanced by culturing with conditioned medium of hepatocytes and cholangiocytes. In future, our group is going to establish the genetically engineered human ES/iPS cells, which carry puromycin resistant cassette under the CYP3A4.
