We find that CD243 (MDR-1) and CD184 (CXCR4) are highly expressed on most all CSC. Please also see our paper on using SmartFlare to label the cells for Sox2 and Nanog live cell mRNA. CD44 high is often reported in the literature as well as ALDH activity. These are for trying to sort the cells via flow cytometry. You can easily put them into sphere culture to grow out the true CSC and enrich/expand the population that way, then just do some flow to confirm the markers. Are you using patient tumors or established cell lines? It can be much more difficult from cell lines and most have lost their CSC populations a long time ago!
