Charité publishes number of laboratory animals for 2022

On the occasion of today's World Day for Laboratory Animals, Charité - Universitätsmedizin Berlin publishes its current number of laboratory animals used in the previous year 2022. These numbers are submitted annually by Charité scientists to the responsible authority, the State Office for Health and Social Affairs (LAGeSo), by March 31. For the year 2022, researchers reported a total of 51,338 animals used in the context of biomedical research questions. The vast majority of these animals were mice (92.8 percent) and rats (5.5 percent).

"Animal experiments are currently still irreplaceable for the further development of medical treatment s. For this reason it is even more important to target research into the development of alternatives," emphasizes Prof. Dr. Stefan Hippenstiel, Professor of Infectious Diseases and Pneumology at Charité and spokesman for Charité 3R. He adds, "Because anyone who conducts research with animals is at the same time obligated to look for alternatives and do everything possible to reduce the burden on laboratory animals as much as possible."

For 2022, a total of 51,338 animals was reported, around 4,000 fewer laboratory animals than for 2021. The decrease is within the range of usual fluctuations, for example, when new research groups are added, larger projects start or are terminated.

More detailed information on animal experimental research at Charité, including all facts and figures on laboratory animals, the species used, and the areas in which the animals were used, can be found on the page Facts and figures on animal experiments at Charité

In addition, two new research stories report on projects in which research is being conducted on mice to find out how daytime and nighttime rhythms affect bone healing and which questions relevant to humans about the the brain can be answered using fruit flies

These and many other exciting projects in which scientists are investigating biomedical issues in animals and alternative methods can be found in the 3R research stories.
