PXB-cells®
Increased translational potential via high quality and fresh on-demand human hepatocytes
In vitro experiments don’t have to produce results that are disconnected from human physiology. With PXB-cells®, you can model human cell biology in your in vitro experiments, enabling you to progress confidently to in vivo studies. Moreover, because PXB-cells® and PXB-mice have the same source of donor hepatocytes, you can directly compare between in vitro cell data and in vivo data collected from PXB-mice.
PXB-cells® are ~95% pure human hepatocytes freshly isolated from the PXB-mouse®. Their high human-specific enzyme and transporter activity can be maintained long-term, providing a superior in vitro model system of the human liver environment. Our stable supply of on-demand PXB-cells® enables you to perform reproducible experiments using the same source of donor hepatocytes.
Applications
PXB-cells® are ideally suited for studies which require the use of primary human hepatocytes, such as drug metabolism, enzyme induction/inhibition, safety assessment, transporter evaluation, anti-HBV therapeutics efficacy testing and other studies.

Our PXB-cells® have helped to drive hundreds of drug discovery projects over the last decade and enabled organizations to achieve accurate human liver data.
Case study: Mitochondrial toxicity with PXB-cells®
- The mitochondrial function of cryopreserved human hepatocytes (CHH) and PXB-cells® were directly compared
- PXB-cells® outperformed CHH lots in terms of energy metabolism and mitochondrial function
