Could animal testing in medicine soon become a thing of the past? Czech scientists are building a lab-grown model of the human intestine that could make drug testing more accurate, ethical and closer to human biology.

At Tomas Bata University in the city of Zlin in Czechia, researchers are cooperating with the Institute of Biophysics of the Czech Academy of Sciences on the development of a lab-grown model of the human small intestine that could transform how new drugs are tested.
