Clonal expansion and progression in acute myeloblastic leukemia

Abstract

Diseaes originating in pluripotent stem cells, then developing through clonal expansion and clonal progression may properly be grouped together because of their common features. Among these, AML appears to be unique by reason of the presence within the clone of a blast cell population. Studies of cellular composition and regulation in AML clones require assays that measure not only myelopoiesis but also blast cell proliferation. The relation of the blast population to other components of AML clones remains uncertain. Resolution of the uncertainty is important in considering therapeutic strategies.
