Cryopreserved Mouse Hepatocytes

PRIMACYT is one of the pioneers in the development of advanced in vitro model systems. We are a leading company in the field of research of human and animal hepatocytes. We offer fresh and cryopreserved animal hepatocytes in suspension and plated.

PRIMACYT is approved by the European Commission as an EU Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM) since 2013 and serves as member of the laboratory network responsible for the method validation.

Our colleagues are professionals and undergo continuous training in the preparation, isolation and cryopreservation of hepatocytes in general, including related co–products, methods and tools. We are a GLP certified laboratory since 2006.

In drug development, at least two in vivo repeated–dose toxicity studies of a drug candidate have to be performed in two different animal species before human studies can be initiated (https://www.fda.gov/downloads/drug /guidancecomplianceregulatoryinformation/guidances/ucm292340.pdf). In most cases these species are mouse or rat and dog or monkey.

Hepatotoxicity is a major cause for failure in drug development. For interpretation of hepatotoxicity data, it is important to understand potential interspecies differences in mechanisms that lead to drug toxicity. This includes
– drug uptake into the liver,
– biotransformation of the drug (Phase I and Phase II), and
– drug efflux from the liver

Interspecies differences in expression and activities in transport proteins and biotransformation enzymes may result in different intra– and extrahepatic concentrations of the drug.

Quantification of drug transporter protein by LC/MS has revealed significant interspecies differences in the expression of uptake and efflux transporters. On the other hand, in beagle hepatocytes expression of the two most important Organic Anion Transporters Oatp1a2 and Oatp1b4 (equivalent to human OATP1B1 and OATP1B3) was maintained at the same level as in dog liver tissue (Wang et al. 2014).

PRIMACYT provides primary mouse hepatocytes and non-parenchymal liver cells for 2D and 3D cell cultures. They mimic hepatocellular functions. 

We offer certified pools of cryopreserved mouse hepatocytes and hepatocytes from single donors. Pooled hepatocytes are obtained from several individual animal liver perfusions performed in parallel.

Each pool and the single donors are comprehensively tested for viability, use in suspension assays and plateability in 2D and 3D cultures.

For selected lots matched non-parenchymal liver cells are available as well.

This info refers to the product data below:

• Inventory: Number of vials available as of date of last update. Availability of vials may have changed since that date by interim orders.
• Viability: Denotes post thaw results using the thawing protocol for hepatocytes.
• Plateability in 2D format is tested on collagen coated 24well and 96well plates, for 3D spheroid cultures ultra-low attachment plates Biofloat™ from faCellitate are used.
