Is vWF a great marker for Endothelial Cells?
Secretory granules called Weibel-Palade bodies (WPBs) containing Von Willebrand factor (vWF) are more linked to the formation of a confluent endothelial monolayer. Research shows that vWF expression is dynamic and highly dependent on the cell culture conditions such as confluence and passage number. Therefore, having vWF as a quality control marker for each lot of ECs is not really necessary.
