We evaluated the following fractions from CML-CP patients or HD samples: CML-CP LSC-enriched (CD34+CD38−CD26+), CML-CP HSC (CD34+CD38−CD26−), CML-CP progenitors (CD34+CD38+), HD HSC (CD34+CD38−/dim), HD progenitors (CD34+CD38+). Here, CD38 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
