CD34 and chronic myelogenous leukemia, BCR-ABL1 positive: Here, to the best of our knowledge, we report for the first time the proteomic and the phospho-proteomic profile of CD34+ cells obtained from CP-CML patients, compared to CD34+ progenitors from healthy donors, showing that the former are characterized by a specific proteomic and phospho-proteomic profile that promotes quiescence and survival.
