CD34 and chronic myelogenous leukemia, BCR-ABL1 positive: Proteomic comparison of CD34+CD38−CD26+ and CD34+CD38−CD26− cells identified increased levels and enrichment of proteins responsible for macromolecule metabolism (PPARD, M3K14, HNF6, and LPH) in CD34+CD38−CD26+ cells, which represent the CML LSC fraction [203].
