IIVS Workshop Series: Identification, Discussion and Recommendations for the Optimal Generation and Use of In Vitro Genotoxicity Assay Data for Tobacco and Nicotine Products
October 18, 2019The Institute for In Vitro Sciences (IIVS) is sponsoring a series of workshops to identify, discuss and develop recommendations for optimal scientific/technical approaches for utilizing in vitro assay data within and across tobacco and nicotine product categories. Workshops provide a unique opportunity for invited expert stakeholders to share experiences and to develop recommendations that may serve as a resource for developing optimal approaches and data to evaluate the toxicity of tobacco and nicotine products. It is envisioned that some of...
Use of Ex Vivo Precision-Cut Lung SLices as a Screening Tool for Potential Respiratory Toxicity of E-Liquids
October 17, 2019The Family Smoking Prevention and Tobacco Control Act gave the FDA regulatory authority over next generation tobacco products (NGTP) such as E-vapor products. E-vapor product liquids contain a variety of ingredient combinations that should be assessed for human risk. One human lung-relevant testing platform with reasonable throughput, is human precision-cut lung slices (HuPCLS). HuPCLS are arguably the most complex non-animal model of the lung, retaining native architecture and immune-competent cells over multi-week culture periods. HuPCLS were exposed to three concentrations...
