Marginal grafts, such as fatty livers, grafts from older donors, or livers retrieved after cardiac death (DCD) tolerate conventional, cold static storage only poorly. We developed a novel model of subnormothermic ex vivo liver perfusion for preservation, assessment, and repair of marginal liver grafts prior to transplantation.

Here, we describe a minimally invasive laparoscopic technique for serial sampling of liver and mesenteric lymph nodes (MLN) in macaques that allows for increased sampling frequency, and reduces the potential for surgical complications when compared to performing a laparotomy.

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.

Portal vein thrombosis (PVT) is a frequent complication in patients with portal hypertension resulting from end-stage liver disease. In certain instances, PVT may be a contraindication for liver transplantation. We have developed a novel approach for managing PVT cases involving complete occlusion of the main trunk of the portal vein.

The ability of metastatic clones to colonize distant sites depends on their proliferation capacity and/or their ability to survive in the host microenvironment without significant proliferation. Here, we present an animal model that allows quantitative visualization of both types of liver colonization by metastatic clones.
FAQs
Heat rapidly transfers into the tissue, raising its temperature enough to denature proteins and reduce enzyme activity. These changes can modify the liver’s physical and biochemical state, which may affect how the sample behaves during later analysis. Interpreting results therefore requires recognizing that some observed features may reflect thermal treatment rather than the tissue’s original condition.
Cooling limits further thermal changes once the intended heat exposure has ended. This helps reduce continued effects on proteins, enzymes, and tissue structure after removal from the heated medium. By stopping or slowing additional change, cooling improves consistency between samples and helps researchers attribute later observations more confidently to the controlled blanching step.
Researchers must balance improved handling and preservation of selected structural features against biochemical changes caused by heating. Greater thermal effects may alter protein behavior and enzyme activity, while insufficient or inconsistent exposure may provide less standardized preparation. The appropriate condition depends on whether the study emphasizes histological appearance, biochemical measurements, imaging, or comparison among samples.
The workflow consists of exposing the liver tissue to hot water or another heated medium under controlled conditions, then cooling it to limit additional thermal effects. After cooling, the prepared sample can proceed to histological, biochemical, or imaging analysis. Consistent handling of the heating and cooling stages is important for making comparisons among specimens meaningful.
This preparation approach is useful when investigators need samples that are easier to handle, have selected structural features preserved, or undergo a more standardized preparation before analysis. It can support studies based on tissue appearance, biochemical properties, or imaging. The method is especially relevant when comparisons require researchers to control a common pre-analysis treatment across samples.
Researchers should interpret findings in light of the tissue’s heat exposure and cooling history rather than treating every observed change as naturally occurring. Protein denaturation, reduced enzyme activity, and altered physical properties can result from preparation itself. Comparing consistently treated samples and accounting for the technique’s effects helps separate treatment-associated findings from underlying liver biology.
