CD38 and chronic myelogenous leukemia, BCR-ABL1 positive: We sorted the CD34+CD38- cells from the AML cell line KG1a (Fig 2A, S2 Fig) and the CML cell line KU812 (Fig 2D, S2 Fig), as LSCs of myelogenous leukemia are considered to be enriched in this fraction, which was also previously reported in leukemia cell lines including KG1a [20, 21].
