Abbreviations: CML, chronic myeloid leukemia; HU, hydroxyurea; m, male; f, female; PB: peripheral blood; BM: bone marrow; CP, chronic phase; BP, blast phase; n.t., not tested; none, no therapy (diagnostic sample); res, resistant; dis, discontinued due to intolerance; µM, micromolar. Responses of cells to HU, palbociclib and `HU + ponatinib´ were assessed by 3H-thymidine uptake.
