VWF and cancer: Several receptors on platelets, EC, and cancer cells have been proposed to provide attachment points for VWF on these cells, in which the major ones are platelet GPIbα, P-selectin, ανβ3 and αIIbβ3 integrins, and glycocalyx (Denis et al., 1993; Sadler, 1998; Padilla et al., 2004; Huang et al., 2009; Zhou et al., 2012; Kalagara et al., 2018).
