Induction of polyploidization in leukemic cell lines and primary bone marrow by Src kinase inhibitor SU6656

Abstract excerpt

Megakaryocytes (MKs) undergo successive rounds of endomitosis during differentiation, resulting in polyploidy (typically, 16-64N). Previous studies have demonstrated that this occurs through an interruption of normal cell cycle progression during anaphase. However, the molecular mechanism(s) controlling this unique process is undefined. In the present report, we examine the effect of an Src kinase inhibitor,...
