CD34 and chronic myelogenous leukemia, BCR-ABL1 positive: Following metabolic profiling of primary chronic myeloid leukemia (CML) cells, Kuntz et al. found a three-fold increase in the rate of mitochondrial oxygen consumption along with a pattern of metabolites indicating increased lipolysis and fatty acid oxidation in the stem cell-enriched population (CD34+CD38−), compared to differentiated CML cells (CD34−) (Kuntz et al., 2017).
