Identification of Syndecan-1 As a Key Dependency of Myeloid Leukemia Growth and Dissemination

Intratumoral heterogeneity is a common feature of many myeloid leukemias and a significant reason for treatment failure and relapse. Thus identifying the cells responsible for residual disease and leukemia re-growth is critical to better understand how they are regulated. Here we show that a knock-in reporter mouse for the stem cell gene Musashi 2 (Msi2) allows identification of therapy resistant leukemia propagating cells in aggressive myeloid...
