The model utilizes an air–liquid interface exposure device, VITROCELL Cloud, which PETA had awarded to the Heriot–Watt group in 2017 along with three other groups, in an attempt to support the development of non-animal toxicity testing methods.


PETA International Science Consortium Ltd (London, UK) – the People for the Ethical Treatment of Animals – has provided funding to support MatTek Life Sciences (MA, USA) in their development of the first nonanimal 3D lung alveolar model of its kind. Called EpiAlveolar™, the model can be used to study the effects of chemical, material or pathogen inhalation on the lung, without the need for animal involvement.
