PETA Science Consortium International and Epithelix invite you to apply to win three-dimensional reconstructed human respiratory tissues from Epithelix. Epithelix’s human cell–based tissue models mimic different regions of the respiratory tract and can be used for testing cosmetics, pharmaceuticals, medical device extracts, industrial chemicals, pesticides, and household products.

The award winner will be selected based on their proposal’s scientific merit and potential to replace the use of animals in inhalation testing, and will receive a $15,000 (~€15,237) award redeemable for Epithelix tissues (MucilAir™, SmallAir™, or AlveolAir™) and/or primary human alveolar macrophages (at standard commercial prices). Researchers from any sector (e.g. industry, academia, and government) are encouraged to apply, and this opportunity is open to applicants worldwide.

Application Requirements

In addition to a curriculum vitae, please submit a proposal (1,000 words or less) addressing the following:

  • Tissues you are requesting (one or more tissue type representing different regions of the respiratory tract)
  • Whether you are currently using Epithelix tissues and/or other models in your research
  • Scientific advantages and limitations of using Epithelix model(s) for your research
  • Information regarding the test substance and endpoints to be assessed
  • How your work will replace the use of animals in inhalation tests
  • Your plan for disseminating the data generated using the Epithelix tissues

The deadline to submit a proposal is 3 February 2023, and the award winner will be announced in March 2023.
