• Paper published in Nature Metabolism demonstrates novel pathway regulating the underlying mechanism of liver fibrosis 
  • Research harnesses CN Bio’s liver-on-chip NASH disease model, to advance development of potential new medicines for liver fibrosis 

CN Bio, a leading cell culture company that has developed single and multi-organ microphysiological systems (MPS) that improve the accuracy and efficiency of drug discoverytoday announced the publication of co-authored research led by researchers at the University of Cambridge in Nature Metabolism1identifying a novel pathway that regulates the underlying mechanism of Non-Alcoholic Steatohepatitis (NASH), potentially a new therapeutic target. The collaborative work uses CN Bio’s NASH model to help elucidate the complex cellular mechanisms that cause liver fibrosis. 

The group demonstrated that Bone Morphogenetic Protein 8B (BMP8B), a poorly characterised member of the BMP/TGFβ superfamilyexhibits marked upregulation during Non-Alcoholic Fatty Liver Disease (NAFLDto NASH disease progression. This surge of BMP8B was shown to be an important mediator of liver disease progression, and a leading pathogenic mediator of the wound healing response of NASH, therefore presenting itself as a potential therapeutic target.

The paper illustrates the direct translation between CN Bio’s NASH assay, human clinical studies and in vivo mouse models. It demonstrates that the MPS NASH model can offer more human-relevant data than standard liver tissue studies, and a quicker and cheaper option to study NASH pathophysiology with similar results to long and expensive animal models to better inform the drug discovery process and reduce associated costs. Cell cultures were performed in CN Bio’s MPS NASH modelutilising its proprietary liver-on-chip technologywhich enables longer term in vitro culture (>1 month) of primary human hepatocytes in 3D microtissue structures. The NASH assay captures all key aspects of thdifferent stages of the NAFLD/NASH spectrum: intracellular fat accumulation, inflammation and fibrosis.  

Dr David Hughes, CEO, CN Bio, commented: “Increasing global levels of obesity are paralleled with growing numbers of NASH patients. However, currently there are no therapies on the market to treat the disease, with candidates in phase 3 clinical trials not effective enough to treat the majority of patients. By providing human-relevant organ-on-chip data, our NASH model is enabling researchers to screen new NAFLD and NASH therapeutic candidates, investigate mechanisms of action and generate actionable data in weeks, ultimately to fast-track investigation into new drug candidates.  

Dr Tomasz Kostrzewski, Director, Biology, CN Bio, said: “This paper demonstrates how industry leaders in fatty liver disease, NASH and fibrosis have recognised the quality of CN Bio’s research and the reliability of our data. We’re excited to see this research published in Nature Metabolism, a new and exciting journal for our field which will become highly impactful.
