Web16 nov. 2006 · This is the main cause of several myeloproliferative disorders, like chronic myelogenous leukemia (CML). In CML the rate of platelet production is abnormal due to malignant megakaryoblast overproliferation. Casein kinase 2 (CK2) plays a crucial role in CML. CK2 was found to interact with BCR/ABL and to modulate its function. Megakaryocytes are derived from hematopoietic stem cell precursor cells in the bone marrow. They are produced primarily by the liver, kidney, spleen, and bone marrow. These multipotent stem cells live in the marrow sinusoids and are capable of producing all types of blood cells depending on the signals they receive.
