摘要: The present invention relates to methods and compositions for culturing embryonic stem (ES) cells. The methods relate to growing the ES cells in the presence of small molecules of formula (I) that maintain the pluripotency/self-renewal of the cells without feeder cells and LIF in serum-free conditions. These methods in part facilitate much more consistency in embryonic stem cell production, providing, for example, new avenues in the practical applications of embryonic stem cells in regenerative medicine.
