| Outline of Final Research Achievements |
We established a cost effective protocol to induce endoderm differentiation with low concentration of Activin by adding DMSO. We found that at the presence of DMSO, the threshold of Activin to induce intestinal differentiation is much reduced. We also established a protocol to selectively culture the human iPS cells-derived intestinal epithelial cells from a mixed cell population, so that the purified cells could be expanded and used for further studies. We also found that using defined growth factors and chemicals, the purified cells could be expanded and further matured. The present studies therefore enabled us to prepare a certain amount of cells that could be used for further studies for establishing regenerative medicine of the intestine.
