How does the human liver work?
The human liver is a complex and vital organ located in the upper right part of the abdomen and is essential for a variety of metabolic processes. It is divided into functional units called lobules, which are made up of specialized cells including hepatocytes, endothelial-, stellate- and Kupffer- cells in a highly organized 3D structure.
The anatomy of the liver
Blood enters the liver through two large blood vessels, the hepatic artery and the portal vein. The hepatic artery supplies oxygenated blood to the liver, while the portal vein carries nutrient-rich blood from the digestive system (and this is the only site in the human body where arterial and veinous blood are directly mixed). The blood flows through small blood vessels called sinusoids, which are lined with endothelial cells. Stellate and macrophage-like Kupffer cells have immunological functions and help clean the blood by removing toxins, nucleic acid and peptide fragments, viruses, and even worn-out red blood cells. The blood finally leaves the liver through the hepatic vein which then runs into the inferior vena cava.

How to work with liver cells in 3D cell culture
Working with liver cells in a 3D environment can provide several advantages over traditional 2D cell culture models. This is because the 3D environment can better mimic the in vivo environment of the liver. This brings numerous advantages including improved cell-cell interactions, better cell differentiation, more accurate drug testing, and the possibility to do repeated-dose drug toxicity or follow liver fibrosis.
One way to use 3D cell culture technology to work with the liver is to create liver spheroids or organoids. Liver organoids can be generated using various techniques, such as by spontaneous or forced aggregation, or by scaffold encapsulation (in alginate, Matrigel™ collagens, etc.).
3D structures can be used to study many aspects of liver function including development, disease modeling (including NASH or fibrosis), cancer, drug screening for efficacy, and toxicology.
How to work with liver organoids
in the ClinoStar
By using the ClinoStar device to study liver cells in a 3D environment, you’ll see how the 3D structure affects the behavior and function of liver cells.
The ClinoStar’s precise control over rotational speed enables you to tailor the culture-conditions to your specific needs. The device is versatile, allowing it to be used with different sample types, including cells (whether primary, stem cells, or cell lines), tissues, and even microorganisms.
