Proteoglycans that are synthesized by vascular endothelial cells contribute to the proliferation, migration, and blood coagulation-fibrinolytic system in vascular endothelial cells. Clarification of the molecular mechanisms for proteoglycan synthesis allows understanding of the regulation of endothelial functions. The research strategy of bioorganometallics analyzes biological systems using organic-inorganic hybrid molecules as tools. The present study found dichloro(2,9-dimethyl-1,10-phenanthroline) zinc(II) and its ligand-modulated perlecan expression in vascular endothelial cells, which depends on the cell density.
