IIVS Posters at SOT 2019

March 18, 2019
Society of Toxicology 58th Annual Meeting March 10-14, 2019 Baltimore, MD Thank you to all who visited us at the 2019 SOT meeting! Respiratory Toxicology: Development of a Method to Measure Cigarette, e-Cigarette and Tobacco Heating Product Skin Staining Increased Throughput and Cryopreservation of Precision-cut Lung Slices Extend the Utility of Human-relevant, 3-Dimensional Pulmonary Test Systems Good In Vitro Method Practices: Shipping Study to Evaluate the Performance of the Labcyte Epi-Model 24 Tissues for Use in the Skin Irritation Test (OECD Test Guideline 439) after...

Increased Throughput and Cryopreservation of Precision-cut Lung Slices Extend the Utility of Human-relevant, 3-Dimensional Pulmonary Test Systems

March 18, 2019
Human-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....

Next Generation Tobacco Products and Skin Staining

March 18, 2019
Next generation tobacco and nicotine products (NGPs) such as electronic cigarettes (EC) and tobacco heating products (THP) have reduced toxicity and hold great potential for reducing the risks associated with cigarette smoking. NGPs may also have hygiene benefits for consumers that switch to these products. In this study, the level of skin staining was assessed following exposure to a scientific reference cigarette (3R4F) and NGPs across the risk continuum; a prototype EC or a commercial THP (glo™). Test articles (TAs) were...

Register For ICCVAM’s Free Webinar on In Vitro Inhalation Toxicity Testing

January 10, 2019
NICEATM 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, 2018
The 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),...

Erin Hill and Rodger Curren from IIVS are both speaking at the event. Learn more about the meeting, including the scientific program, invited speakers, and how to register.  ...

Next-Generation Tobacco and Nicotine Products: Substantiating Harm Reduction and Supporting Tobacco Regulatory Science

June 21, 2018
A 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, 2018
The 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...
