Platelet-producing megakaryocytes go through endomitosis during cell differentiation
Megakaryocytes are derived from ................... stem cell
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.
The primary signal for megakaryocyte production is -
The primary signal for megakaryocyte production is thrombopoietin
