Abstract

In this article, we provide an overview of the experimental workflow by the Lung and Particle Research Group at Cardiff University, that led to the development of the two in vitro lung models - the normal human bronchial epithelium (NHBE) model and the lung-liver model, Metabo-Lung™. This work was jointly awarded the 2013 Lush Science Prize. The NHBE model is a three-dimensional, in vitro, human tissue-based model of the normal human bronchial epithelium, and Metabo-Lung involves the co-culture of the NHBE model with primary human hepatocytes, thus permitting the biotransformation of inhaled toxicants in an in vivo-like manner. Both models can be used as alternative test systems that could replace the use of animals in research and development for safety and toxicity testing in a variety of industries (e.g. the pharmaceutical, environmental, cosmetics, and food industries). Metabo-Lung itself is a unique tool for the in vitro detection of toxins produced by reactive metabolites. This 21st century animal replacement model could yield representative in vitro predictions for in vivo toxicity. This advancement in in vitro toxicology relies on filter-well technology that will enable a wide-spectrum of researchers to create viable and economic alternatives for respiratory safety assessment and disease-focused research.
