In megakaryocyte polyploidization, the cell cycle-related protein and cytoskeletal proteins both play important role in MK endomitosis. It is suggested that G1 phase progression protein cyclin D1 and G1/S checkpoint protein cyclin E1 are both essential for DNA content enlargement and megakaryocyte polyploidy.
