Moreover, when the frequencies of SSCloNCPs in the BM of CP-CML patients were related to CD34+CD34dim/- cells, the number of SSCloCD45RA-NCP4s was significantly greater than that in the BM of HDs (Fig. 7C) or SM patients (Fig. S4B). This evidence concerns the gene CD34 and chronic myelogenous leukemia, BCR-ABL1 positive.
