  Cancer stem-like cells (CSC) have garnered significant attention as a therapeutic focus, based on evidence they may represent an etiologic root of treatment-resistant cells.Indeed, expression of the multidrug resistance protein ABCG2 confers chemoresistance to CSC where it serves as a potential biomarker and therapeutic target.Here we show that afatinib, a small molecule inhibitor of the tyrosine kinases EGFR, HER-2 and HER-4, preferentially eliminated side population (SP) cells with CSC character, in both cell lines or patient-derived leukemia cells, by decreasing ABCG2 expression.
