Experts are confident that the use of artificial human organs could replace animal testing in as little as three years and herald the closure of animal-testing laboratories worldwide.
Artificial organs, such as lungs, liver and kidneys, are already being used to test cosmetics, chemicals and drugs.
Now experts are confident the replacement will close down the majority of animal testing laboratories.
Uwe Markx, a tissue engineer from Technische Universitat Berlin and founder of TissUse, said: “If our system is approved by the regulators, then it will close down most of the animal-testing laboratories worldwide.”
Scientists from Harvard University are already developing a five-organ version to test medical conditions such as asthma.
Geraldine Hamilton, senior staff scientist at the university’s Wyss Institute, said: “We are replacing animal testing right now.
“These systems allow a much greater understanding of the mechanisms of the human body and give us insights that are not possible with animal studies.”
Organ farms will eliminate the need for routine animal testing, but 20% of the testing will continue on animals for conditions including Alzheimer’s disease and hip-replacement therapy.
