In 2017, the PETA Science Consortium International awarded four VITROCELL in vitro exposure systems to researchers from institutions in the UK, US, and Belgium who are leading the development of non-animal methods to test the toxicity of airborne substances.
VITROCELL offers a variety of devices that allow cultured cells to be exposed to substances (e.g. cigarette smoke, nanomaterials, and other chemicals) at the air-liquid interface, mimicking realistic human exposure.
The VITROCELL exposure systems were donated to the following laboratories working to reduce and replace the use of animals in inhalation testing:
- Belgium-based VITO NV
- North Carolina-based ScitoVation
- Maryland-based Institute for In Vitro Sciences (IIVS) to study tobacco products, including e-cigarettes
- Professor Vicki Stone at Edinburgh’s Heriot-Watt University to advance the Consortium’s ongoing project to develop a non-animal system for predicting lung fibrosis in humans
In 2019, following a resounding need for IIVS to expand its capabilities, the PETA Science Consortium International donated another device that can be used to meet the needs of the personal care industry, and partnered with tobacco companies to donate equipment that would allow IIVS to expand their testing of tobacco products.
In June 2021, PETA Science Consortium International and MedTec Biolab, Inc., awarded the Canadian Centre for Alternatives to Animal Methods a free CelTox Sampler. Manufactured by MedTec Biolab, the device can be used to expose in vitro lung cell models to a variety of substances (e.g. chemicals, cigarette smoke, or nanomaterials) at the air-liquid interface, mimicking human exposure.
The CelTox Sampler will be used to assess the acute inhalation toxicity of chemicals in vitro using a novel, three-dimensional, bioprinted human respiratory tract tissue model (Alveoli-in-a-Dish) developed at the centre.
These awards and donations complement the Science Consortium’s ongoing efforts to replace animal use in inhalation testing, including various workshops and webinars.
