Enrichment of cancer stem cells under ES culture condition. Melanoma cell lines cultivated in standard medium (A) and ES medium (C) were incubated with Hoechst 33342 and analyzed for Hoechst dye emission. Whereas in standard medium no side population of putative cancer cells were detected, a side population of more than 6% emerged under ES cell condition Verapamil control (B and D).
