PETA Science Group and Tobacco Companies Donate to Save Animals
August 28, 2019Donated Equipment Will Help to Replace Animals in Respiratory Toxicity Testing Gaithersburg, MD — The PETA International Science Consortium Ltd., Imperial Brands PLC, Altria Client Services (ALCS), British American Tobacco PLC, and Philip Morris International Inc have joined together to donate equipment that can help to replace the use of animals in respiratory testing with more human-relevant, non-animal test methods. The equipment — worth $110,000 and manufactured by Germany-based VITROCELL Systems — was donated to the Institute for In Vitro Sciences (IIVS),...
See You at EUROTOX 2019!
August 15, 2019IIVS is excited about meeting attendees of the 55th EUROTOX conference! Please join us at booth #34 to meet our representatives who are looking forward to discussing trends and New Methodologies in Alternative Approaches (NAMs) to toxicological research, as well providing updates on services offered by our organization! Also, don’t miss our posters: The kinetic Direct Peptide Reactivity Assay (kDPRA): An in chemico method to characterize the skin sensitization potency of chemicals (Poster Viewing 1) Increased Throughput and Cryopreservation of Precision-Cut Lung...
Increased Throughput and Cryopreservation of Precision-cut Lung Slices Extend the Utility of Human-relevant, 3-Dimensional Pulmonary Test Systems
March 18, 2019Human-relevant, in vitro/ex vivo assays are considered an ethical and economically viable manner by which to screen the thousands of chemicals requiring hazard assessment. Of the 3-dimensional models, human precision-cut lung slices (PCLS) are often considered the most physiologically relevant pulmonary test system, but lower throughput and difficulties in cryopreservation have hampered PCLS use. We have modified a tissue slicer to accommodate 3 tissue cores for simultaneous slicing. Increased slice production was quantified using agarose and tissue cores in the slicer....
Register For ICCVAM’s Free Webinar on In Vitro Inhalation Toxicity Testing
January 10, 2019NICEATM will organize a free webinar on behalf of ICCVAM on January 22, 2019 between 1:00-2:30 p.m. Eastern Time. Registration will be required. Topics will include an overview of ongoing collaborative efforts, as well as the presentation of a case study on refining inhalation risk assessment for point of contact toxicity that uses a source-to-outcome approach with both in vitro and in silico methods. The preliminary agenda and additional information about presentations will be posted when available....
Tobacco Companies Embracing In Vitro Toxicology
October 29, 2018The tobacco industry is facing increased testing requirements for e-cigarettes and other tobacco products that entered the market after Feb. 15, 2007. Companies hope in vitro tests that use human lung cells or tissues will be sufficient to show that their new tobacco products, including e-cigarettes, significantly reduce harm and disease and benefit the population as a whole when compared with traditional cigarettes. Several of them are working with independent, third-party laboratories, including the Institute for In Vitro Sciences (IIVS),...
Webinar: Precision-cut Lung Slices
October 5, 2018Dr. Holger Behrsing, Principal Scientist with IIVS, recently presented "Precision-cut Lung Slices (PCLS)" for the 2018 PETA International Science Consortium webinar series on non-animal inhalation testing methods. ...
Next-Generation Tobacco and Nicotine Products: Substantiating Harm Reduction and Supporting Tobacco Regulatory Science
June 21, 2018A framework for the assessment of novel next-generation tobacco and nicotine products with the potential to reduce health risks compared with cigarettes should integrate scientific studies incorporating nonclinical, clinical, and population studies approaches. These products should have lower emissions and exhibit reduced biological effects compared with those of cigarettes, ideally approaching those of smoking cessation. The products should also be acceptable cigarette alternatives for current smokers, while not appealing to nonsmokers or former smokers. Validating harm reduction and promoting regulatory acceptance...
Characterization of a Vitrocell VC1 Using Nicotine Dosimetry: An Essential Component Toward Standardized In Vitro Aerosol Exposure of Tobacco and Next Generation Nicotine Delivery Products
June 21, 2018The U.S. Food and Drug Administration has regulatory authority over tobacco products, including conventional cigarettes and next generation products (NGPs) such as e-cigarettes and tobacco heating products (THPs). There is a desire by the industry, regulators and animal protection organizations to incorporate non-animal test methods for tobacco product and NGP assessment. When assessing respiratory effects in vitro, reliable exposure systems that deliver aerosols to cellular/tissue cultures (such as human reconstructed airways or lung slices) at the air–liquid interface are needed. Using nicotine dosimetry, we report the...
Holger Behrsing, PhD, Participates in Round Table Discussion on Non-Animal Approaches for Inhalation Toxicology
June 14, 2018Holger Behrsing, PhD, was recently invited to participate in an expert round table discussion convened on the development and implementation of 21st century non-animal approaches to assess the toxicity of inhaled substances. The discussion included perspectives from government, industry, nonprofit, and academic sectors on the advantages and challenges of using these approaches, ongoing efforts, and steps needed to gain widespread use and acceptance of these approaches. A transcript of the discussion has just been published in Applied In Vitro Toxicology, Vol....
