The study of liver sinusoidal endothelial cells (SECs) must be performed with primary cells obtained from the animal as no cell lines exist. This method relies on liver digestion and differential centrifugation for SEC purification for subsequent culturing and experimentation.

The fenestrated liver sinusoidal endothelial cell is a biologically important filter system that is highly influenced by various diseases, toxins, and physiological states. These changes significantly impact on liver function. We describe methods for the standardisation of the measurement of the size and number of fenestrations in these cells.

Here we outline and demonstrate a protocol for primary mouse liver sinusoidal endothelial cell (LSEC) isolation. The protocol is based on liver collagenase perfusion, nonparenchymal cell purification by low-speed centrifugation, and CD146 magnetic bead selection. We also phenotype and characterize these isolated LSECs using flow cytometry and scanning electron microscopy.

The goal of this protocol is to obtain high viability and high yield of hepatocytes and sinusoidal endothelial cells from liver. This is accomplished by perfusing the liver with a type IV collagenase solution via the portal vein, followed by differential centrifugation to obtain hepatocytes and sinusoidal endothelial cells.

We provide a method for isolating and culturing pure populations of heart valve endothelial cells (VEC). VEC can be isolated from either side of the cusp or leaflet and immediately following, underlying interstitial cell (VIC) isolation is straightforward.
FAQs
Fenestrations create small openings that allow plasma solutes and blood-borne signals to pass more readily between sinusoidal blood and liver tissue. This architecture helps determine which substances can reach hepatocytes and how strongly those cells are exposed to circulating inputs. Consequently, fenestration structure is important when studying hepatic filtration, metabolism, and responses to substances in the bloodstream.
A discontinuous or absent basement membrane provides fewer structural barriers between sinusoidal blood and the surrounding liver tissue. Together with fenestrations, this arrangement supports close exchange while still allowing endothelial cells to regulate access. Changes to this specialized interface can therefore affect hepatocyte exposure, filtration behavior, and the interpretation of liver injury or disease models.
Their position at the blood-tissue interface allows liver endothelial cells to influence how circulating signals and substances reach liver tissue. By controlling this exposure, they can affect processes associated with inflammation and metabolism without functioning merely as a passive vessel lining. This makes them important cellular components in studies of hepatic responses to blood-borne factors.
Researchers examine these cells as part of the hepatic response to injury and fibrosis, because changes at the sinusoidal interface can influence communication between blood and liver tissue. Such studies help connect endothelial structure and function with disease-related processes. The cells therefore provide a relevant focus for investigating how liver damage alters filtration, signaling, and tissue behavior.
Because these cells regulate exchange between circulating blood and liver tissue, they are relevant to studies of how drug-related substances reach hepatic cells. Their fenestrated architecture provides a biological context for evaluating access from the bloodstream to liver tissue. Drug-delivery research can therefore use this interface to assess hepatic exposure and the effects of endothelial organization.
Engineered liver models can include liver endothelial cells to represent the specialized vascular interface that influences exchange with hepatocytes. Their presence helps models address filtration, blood-borne signaling, inflammation, and metabolism rather than focusing on hepatocytes alone. This broader cellular context may improve investigations of liver function, injury, fibrosis, and responses relevant to therapeutic research.
