Abstract
Melanoma is one of the most aggressive and extremely resistant to conventional therapies neoplasms. Recently, cellular resistance was linked to the cancer stem cell phenotype, still controversial and not well defined. In this study, we utilized a Rhodamine 123 (Rh123) exclusion assay to functionally identify stem-like cells in metastatic human melanomas and melanoma cell lines. We demonstrate that a small subset of Rh123-low-retention (Rh123low) cells is enriched for stem cell-like activities, including the ability to self-renew and produce non-stem Rh123high progeny and to form melanospheres, recapitulating the phenotypic profile of the parental tumor.
