Granulocyte–Macrophage Progenitors as Candidate Leukemic Stem Cells in Blast-Crisis CML

Abstract
The progression of chronic myelogenous leukemia (CML) to blast crisis is supported by self-renewing leukemic stem cells. In normal mouse hematopoietic stem cells, the process of self-renewal involves the β-catenin–signaling pathway. We investigated whether leukemic stem cells in CML also use the β-catenin pathway for self-renewal.
