Ruben Bierings is an endothelial cell biologist and Associate Professor in the Department of Hematology. He received his PhD from Utrecht University for his work on Von Willebrand factor secretion in endothelial cells (2007, thesis “Sorting out the Weibel-Palade body), which was carried out at CLB-Sanquin Research in Amsterdam. He completed postdoctoral research as an MRC Career Development Fellow (2007-2011) at the National Institute for Medical research (NIMR) in London (UK). Upon his return to the Netherlands he started his own lab, first at Sanquin Research and Landsteiner Laboratory, Amsterdam UMC, but since 2018 at Erasmus MC. He serves as a co-chair of the International Society for Thombosis and Haemostasis (ISTH) Vascular Biology Scientific Standardization Subcommittee (SSC). Research in the Bierings lab revolves around the molecular mechanisms of Von Willebrand factor secretion, biogenesis and exocytosis of Weibel-Palade bodies and how defects in these process can give rise to bleeding abnormalities in patients.


Our research

In our lab we study the molecular mechanisms of secretion in endothelial cells and platelets in order to understand how defects in these mechanism can lead to bleeding disorders.

Using innovative (patient-derived) cellular model systems such as blood outgrowth endothelial cells (BOECs) and induced pluripotent stem cells (iPS)-derived megakaryocytes we are systematically investigating the mechanisms that control how secretory organelles such as endothelial Weibel-Palade bodies (WPBs) or platelet alpha- and dense granules are formed and how they acquire the molecular machinery to undergo exocytosis.
