Abstract:Intrinsic and extrinsic signals together contribute to determine self renewal, quiescence or the specific metabolic status of leukemic stem cells (LSC) in BCR-ABL mediated chronic myeloid leukemia (CML). Our previous studies have shown that expression of BCR-ABL together with the polycomb repression complex 1 member BMI1 in human CD34+ cells is sufficient to induce a serially transplantable lymphoid leukemia in vivo while a myeloid phenotype was never observed. Yet in vitro, both lymphoid as well as myeloid im… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
