Abstract: The present invention relates to methods and compositions concerning isolation of proliferating cells. In particular, the invention regards enrichment of stem cells in a mixture of stem cells and non-stem cells, wherein the non-stem cells may be differentiated cells. The invention exploits the non-adherent property of stem cells, as opposed to the adherent property of differentiating cells, by serially passaging the suspended cells in liquid media.
