A tiny gland built from human cells can protect us from chemical dangers and reduce animal testing.
The thyroid gland produces many of the body’s essential hormones, but chemicals found in food, clothes and furniture can interfere with its function. Predicting the toxicity of these chemicals – especially at low doses – has proven difficult. The EU-funded SCREENED project created a model thyroid made of human cells to provide more accurate testing, as well as reduce reliance on animal studies.
