Intratumoral heterogeneity and subclonal diversity, characterized by the coexistence of genetically and functionally distinct leukemic cell populations within a single patient, have long been recognized as major contributors to chemotherapy resistance and disease relapse in acute myeloid leukemia. In this issue of Blood Cancer Discovery, Karigane and colleagues delve into the mechanisms that underlie the interactions between distinct leukemic subpopulations and identify Interferon signaling as a critical regulator that determines clonal dominance and expansion. See related article by Karigane et al., p. 68.
