Multiscale Stiffness of Human Emphysematous Precision-Cut Lung Slices

IIVS is excited to announce a new publication in Science with co-authors at Boston University and Mechanobiologix (Newton, MA, USA)! Abstract: Emphysema is a debilitating disease that remodels the lung leading to reduced tissue stiffness. Thus, understanding emphysema progression requires assessing lung stiffness at both the tissue and alveolar scales. (more…)

Key Challenges and Recommendations for In Vitro Testing of Tobacco Products for Regulatory Applications: Consideration of Test Materials and Exposure Parameters

The Institute for In Vitro Sciences (IIVS) is sponsoring a series of workshops to identify, discuss and develop recommendations for optimal scientific and technical approaches for conducting in vitro assays, to assess potential toxicity within and across tobacco and various next generation nicotine and tobacco products (NGPs), including heated tobacco products (HTPs) and electronic nicotine delivery systems (ENDS).

Evaluating the Use of Predictive Models in Combination with In Vitro Assays

IIVS is excited to announce the publication of 2 papers evaluating the use of predictive models in combination with in vitro assays to provide a quantitative assessment of skin sensitization potential. This work is presented Drs. Frank Gerberick (GF3 Consultancy, Chief Scientific Advisor to IIVS) and Andreas Natsch (Senior Research Fellow at Givaudan ) (more…)

Use of alternative test methods in a tiered testing approach to address photoirritation potential of fragrance materials

Happy New Year! IIVS is pleased to greet 2022 with the announcement of a joint publication with the Research Institute for Fragrance Materials (RIFM) involving the evaluation of photoirritation potential of over 100 compounds. This effort, spanning the course of 7 years, involved a tiered testing approach with the application of 3 OECD test guidelines: TG 101, 432 and the recently accepted 498, which codifies the acceptance of Reconstructed human Epidermis as a model for assessing this endpoint.

How a GIVIMP Certification Program Can Increase Confidence in In Vitro Methods

Regulatory bodies, validation authorities, method developers, and industry toxicologists realize the need to increase confidence in the scientific validity of novel in vitro methods – especially those being proposed for regulatory application .

Acute Electronic Vapour Product Whole Aerosol Exposure of 3D Human Bronchial Tissue

IIVS is excited to have taken part in a new publication highlighting the use of non-animal methods to compare cellular and molecular responses of tobacco smoke and Electronic Vapor Product aerosols. Read and Download the open access article here.

Tiered In Vitro Testing Strategy For Assessing The Ocular and Dermal Irritation/Corrosion Potential of Pharmaceutical Compounds

Read our latest publication with Bristol-Myers Squibb regarding a tiered testing strategy for occupational hazards of pharmaceutical intermediates now published in the Cutaneous and Ocular Toxicology Journal. Irritation reactions are a frequently reported occupational illness. The potential adverse effects of pharmaceutical compounds (PCs) on employees' eyes and skin can now be assessed using validated in vitro methods. Our overall aim is to reduce animal testing by replacing the historically utilized in vivo test methods with validated in vitro test methods which accurately determine the ocular and dermal irritation/corrosion potential of PCs to inform worker safety within the pharmaceutical space. BMS and IIVS have therefore conceptualized and internally qualified a tiered in vitro testing strategy to inform occupational hazards regarding eye and skin irritation and corrosivity of PCs. which is based on three Organisation for Economic Co-operation and Development (OECD) in vitro methods (OECD TG 435, OECD TG 437, OECD TG 439.)
