Optimization of this protocol was partially funded by a grant from Hepacult GmbH. Dr. Wolfgang Thasler is one of the founders of Hepacult GmbH and remains one of the members of the board in this company. The employment of Maresa Demmel is partially by Hepacult. Maria Hauner is employed by Hepacult GmbH. Hepacult is a spin-off biotechnological firm from the University, which offers human hepatocytes with consent and open access for research purposes.

This protocol results in the isolation of human hepatocytes with high viability and purity. In order to achieve these results, it is important to start with a suitable piece of liver. The piece of liver should have intact Glisson's capsule on all surfaces except for 1 cut surface. Another important factor is the particular batch of collagenase used, as different batches can result in marked differences in viabilities of hepatocytes after digestion 11. Therefore, different batches of collagenase should be teste...

Erratum: Isolation of Human Hepatocytes by a Two-step Collagenase Perfusion Procedure

A liver cell suspension can be prepared from the liver by mechanical or enzymatic methods. Mechanical methods used to prepare whole liver cells include forcing the liver through cheesecloth 2, shaking a liver piece with glass beads in a Kahn shaker 3, using glass homogenizers with loose pestles 4,5 etc. Over the years, mechanical methods have fallen out of favor due to the damage to cell membranes and the loss of function of the isolated hepatocytes 6,7. Consequently, the use of an enzymatic method is currently the main method for isolation of hepatocytes.
Isolation of hepatocytes using an enzymatic method was greatly improved when Berry and Friend 8 perfused collagenase and hyaluronidase through the liver via the portal vein in rats. This perfusion process utilized the vasculature to allow the enzymes to come into close contact with the majority of the cells, leading to a 6-fold increase in yield of hepatocytes 8. Further, this method yielded cells that retained their structural integrity, with virtually no transformation of endoplasmic reticulum into isolated vesicles and no mitochondrial damage 8.
This method was modified by Seglen 1, who pioneered a two-step perfusion procedure for liver cell isolation. In this procedure, the rat liver is perfused with a Ca2+ free buffer followed by perfusion with a collagenase buffer containing Ca2+ 1. The removal of Ca2+ in the first step helps to disrupt desmosomes, while the addition of Ca2+ in the second step is required for optimum collagenase activity 1,9.
Given that the published work described above has been performed in rats, this article aims to demonstrate a modified procedure that can be used for isolation of hepatocytes with high viability from human livers. The use of human hepatocytes remains important for translational research and for validating experiments using animal models. The human liver pieces used in this study were acquired with consent for governance through the Human Tissue and Cell Research Foundation, a state-controlled non-profit foundation 10. After a pathologist removed what was required for diagnosis, liver pieces were collected from the remaining tissue. The tissue sectioned off by the pathologist was morphologically healthy tissue obtained from resection margins after liver resection.

isolation of human hepatocytes by a two-step collagenase perfusion procedure

The liver, an organ with an exceptional regeneration capacity, carries out a wide range of functions, such as detoxification, metabolism and homeostasis. As such, hepatocytes are an important model for a large variety of research questions. In particular, the use of human hepatocytes is especially important in the fields of pharmacokinetics, toxicology, liver regeneration and translational research. Thus, this method presents a modified version of a two-step collagenase perfusion procedure to isolate hepatocytes as described by Seglen 1.
Previously, hepatocytes have been isolated by mechanical methods. However, enzymatic methods have been shown to be superior as hepatocytes retain their structural integrity and function after isolation. This method presented here adapts the method designed previously for rat livers to human liver pieces and results in a large yield of hepatocytes with a viability of 77&plusmn;10%. The main difference in this procedure is the process of cannulization of the blood vessels. Further, the method described here can also be applied to livers from other species with comparable liver or blood vessel sizes.
