Abstract
The present application discloses methods expanding SCs in an undifferentiated state, the methods comprising incubating undifferentiated SCs in suspension within a culture system comprising basic medium and knockout serum replacement (KOSR). The methods may also be applicable for selective spontaneous or directed differentiation of SCs into a selected population of somatic cells from a culture system of SCs in suspension, the method further comprising incubating said undifferentiated SCs in culture system that support respectively, spontaneous or directed differentiation of SCs into the selected population of somatic cells. The present application also discloses a culture system for expansion of stem cells (SCs) comprising a suspension of undifferentiated stem cells within basic medium and knockout serum replacement (KOSR). The methods and culture system of the invention may be used for large scale production of differentiated cells.
