Abstract
The present invention relates to the detection of tumor stem cells and tumor cells in epithelial-mesenchymal transition and uses of such methods. According to the present invention said method comprises a selecting step for selection or enrichment of said predetermined cells from the sample wherein the sample is contacted with the solid surface for preferential binding of said predetermined cells to the solid surface and then the sample is removed d from the solid surface in a washing step. The inventive method is characterized in that the sample contains a polyol at least during one of contacting the sample with the solid surface and the washing step and in a detection step detecting in said cells, preferentially selected or enriched by said selecting step, the presence or absence of expression of at least one marker associate with at least one the group comprising tumor stem cells and tumor cells in epithelial-mesenchymal transition.
