Precision Digital Dispensing of Patterned Picoliter Quantities of Test Material onto Apical Surfaces of Human 3D-Reconstructed Airway Tissues

March 30, 2017
There is an increasing need for researchers to understand the dynamic aspects of inhaled tobacco product exposure. Available 3D human reconstructed airway tissues (RHuA) provide researchers with a more physiological platform that offers apical and basal compartments for flexibility in modelling relevant exposures. We have tested the Tecan D300 digital dispenser as potential technical solution to deliver precise amounts of very small vehicle droplets to coat the apical surface of an available RHuA....

The Use of Human 3D Reconstructed Airway Cultures for Tobacco Product Evaluation: Precision Low-Volume Exposures at the Apical Site

January 10, 2017
With a mandate to evaluate the dynamics of pulmonary exposure to inhaled materials such as tobacco-based products, researchers are employing complex, human, three-dimensional pulmonary models. Human reconstructed airway (RHuA) tissues present a platform that more closely resembles airways in vivo. Grown at the air–liquid interface (ALI), RHuA tissues offer apical and basal compartments that allow flexibility in modeling physiologically relevant exposures and provide sampling location-specific results.

Webinar: How GLPs Enhance the Quality of Regulated and Non-Regulated Toxicology

October 18, 2016
This one-hour webinar, led by IIVS Director of Quality and Compliance, introduces some of the concepts of Good Laboratory Practices (GLPs) designed to promote study and data integrity within an in vitro toxicology framework. Applying these concepts within your own laboratory should aid in production of robust, repeatable studies. View Slides...

Next Generation Tobacco Products

August 24, 2016
IIVS has a long-standing history of working with various industries to help establish or utilize in vitro models for the prediction of risk and the assessment of products under development. With the Food and Drug Administration extending its authority to all tobacco products (including e-cigarettes, cigars, and hookah) the tobacco industry is faced with the task of assessing product safety for product development and regulatory submission. Further, the manufacture of tobacco products may entail risk to workers that come in...

IIVS Workshop Explores Exposure and Dosimetry Considerations for Non-animal Testing

April 12, 2016
GAITHERSBURG, MD – April 12, 2016 – The Institute for In Vitro Sciences (IIVS) brought together stakeholders from industry, government and academia to discuss considerations for exposure and dosimetry for non-animal testing during its 2.5-day workshop, “In Vitro Exposure Systems and Dosimetry Assessment Tools for Inhaled Tobacco Products”, held April 4-6, 2016 in Bethesda, MD. Uniquely focused on in vitro testing, the workshop is the only known event of its kind. Attendees, including toxicologists from industry, the FDA Center for Tobacco...
