CP and chronic myelogenous leukemia, BCR-ABL1 positive: Comparative analysis of cell cycle transit in NP versus CP CML CD34+ cells demonstrated that CP CD34+ CML cells (11 out of 17 cells) harbored significantly longer G1 phase transit times (p-value 0.0014; Fisher’s exact test) compared with normal progenitor counterparts (Supplementary Fig. 3b,c).
