Pieter KoolwijkAssistant Professor

Research focus

Vascular aspects of Tissue Engineering

Pieter Koolwijk studied Medical Biology at the University of Amsterdam and received a PhD degree from the University of Utrecht in 1990 for his studies on the characteristics of bispecific monoclonal antibodies. From November 1989 till March 2006 he was projectleader/senior investigator at Gaubius Laboratory TNO-QoL in Leiden, where he studied the involvement of proteolytic enzymes, matrix components and hypoxia on the process of angiogenesis. During this period his group developed many in vitro and in vivo angiogenesis models, and he was, as projectleader, responsible for the coordination of contract research in the field of angiogenesis for pharmaceutical companies.  In April 2006, he and a part of his group moved to the Institute for Cardiovascular Research VU (ICaR-VU), Dept. for Physiology, VUMC in Amsterdam, and continued his work on the involvement of hypoxia and temporary fibrin matrices on angiogenesis. In collaboration with Victor van Hinsbergh’s group, his group has made important contributions on the effect of chronic hypoxia on endothelial cell functions and endothelial cell progenitor differentiation/outgrowth in relation to vascularization of tissue-engineered tissue constructs.
