Abstract This review provides a detailed overview of the current state of knowledge about the ultrastructure and dynamics of liver sinusoidal endothelial fenestrae. Various aspects of liver sinusoidal endothelial fenestrae regarding their structure origin species specificity dynamics and formation will be explored. In addition the role of liver sinusoidal endothelial fenestrae in relation to lipoprotein metabolism fibrosis and cancer will be approached. Introduction Liver sinusoidal endothelial cells LSEC constitute the sinusoidal wall also called the endothelium or endothelial lining. The liver sinusoids can be regarded as unique capillaries which differ from other capillaries in the body because of the presence of open pores or fenestrae lacking a diaphragm and a basal lamina underneath the endothelium. The first description and electron microscopic observation of LSEC fenestrae was given by Wisse in 1970 1 . The application of perfusion fixation to the rat liver revealed groups of fenestrae arranged in sieve plates. In subsequent reports Widmann 2 and Ogawa 3 verified the existence of fenestrae in LSEC by using .
