| Research Abstract |
Human Embryonic Stem(hES) cells and human induced Pluripotent Stem(hiPS) cells are commonly maintained on inactivated mouse embryonic fibroblast as feeder cells in medium supplemented with FBS or proprietary replacements. Use of culture media containing undefined or unknown components has limited the development of applications for pluripotent cells because of the relative lack of knowledge regarding cell responses to differentiating growth factors. Therefore we developed a serum-free medium, designated hESF9, in which human ES cells can be maintained in undifferentiated state without feeder cells. We have developed a serum-free defined medium for culturing hiPS cells, which can maintain proliferation, self-renewal and pluripotency. As this simple serum-free adherent monoculture system will allow us to elucidate the cell responses to growth factors under defined conditions, and can eliminate the risk might be brought by undefined pathogens.
