abstract：:In most eukaryotic cells, a link between S and M phases of the cell cycle must be assured in order to maintain the ploidy of newly divided cells. However, in some cell l/pes, e.g. the precursors of platelets megakaryocytes, extra S-phases can occur in the absence of concomitant mitoses, resulting in polyploidy. We hav...
