| Outline of Final Research Achievements |
Human pluripotent stem cells including ES and iPS cells have ability of infinitely self-renewal and differentiation into all major lineages of cells in the human body. A chemically-defined culture system, free of any biomaterials, is the ideal platform for the quality-controlled, large-scale, cost-effective production of human pluripotent stem cells for use in cell-based therapy and drug discovery. One major objective in developing such a system is to reduce the costs associated with recombinant proteins used as supplements in basal culture media. In this project, we have developed a a defind culture system including growth factor-free culture medium utilizing only three chemical compounds and the least number of recombinant proteins of any other commercially available medium. This culture system may serve as a new benchmark for the development of completely xeno-free, chemically defined, synthetic culture systems.
