Researchers at EARA member Wageningen University & Research, Netherlands, have developed mini-organs for testing new medicines, reducing the need for animal testing.
Although organ-on-a-chip technology is growing in popularity and is more widely used in other areas of biomedical research, its use in toxicity testing for drugs is currently limited.
Current 2D cell-based models for toxicity testing cannot reflect the complexity of a whole organ, and so, in partnership with Unilever, the team aimed to produce 3D mini-organs which included a number of different cell types and structures, that more closely resemble the human body.
“We want to show that our mini-organs, combined with computer modelling, can provide an adequate simulation of human tissue functions and biological reactions to chemicals,” says Dr Hans Bouwmeester of the Wageningen Toxicology department.
