Behavioural analysis in mice: more precise results despite fewer animals

Researchers are utilising AI to analyse the behaviour of laboratory mice more efficiently and reduce the number of animals in experiments

20-Nov-2024 - There is one specific task that stress researchers who conduct animal experiments need to be particularly skilled at. This also applies to researchers who want to improve the conditions in which laboratory animals are kept. They need to be able to assess the wellbeing of their animals based on ...

A "molecular" compass shows the way to reducing animal testing

Scientists develop intelligent software tool for assessing chemical risks

22-Aug-2024 - In recent years, machine learning methods have become increasingly important for the risk assessment of chemical compounds. However, they are also a "black box" due to a lack of traceability and transparency, which leads to skepticism among experts and regulatory authorities. In order to increase ...

Skin models as an alternative to animal testing

A Fraunhofer start-up aims to significantly reduce animal testing with skin models grown from human stem cells

05-Jun-2024 - Animal testing has long been a fixture of medical and pharmaceutical research, but alternative methods are growing more and more important. Innovative methods allow for research aimed directly at humans — without using animal testing as an intermediate step. TigerShark Science, a planned ...

Replacement for animal testing - now completely without animal suffering

First tissue model of the liver produced entirely without materials of animal origin

10-May-2024 - Scientists at TU Berlin have used 3D bioprinting to produce a model of the liver from human cells for the first time without having to resort to materials of animal origin. This success is an important step towards biomedical research and teaching that is based entirely on methods without animal ...

Using metabolomics for assessing safety of chemicals may reduce the use of lab rats

"We hope that learnings from this research will be included in new guidance for the chemical industry to allow commercial laboratories to provide these services widely"

26-Feb-2024 - Scientists have discovered a more robust way of grouping chemicals and using read-across for toxicological data to meet regulatory requirements, which could greatly reduce animal testing. The safety of chemicals is taken incredibly seriously by regulators and as such industry must meet certain ...

Lab-grown canine skin provides a canvas for testing medical treatments

Eliminating the need for animal testing

05-Feb-2024 - Reproducible in-vitro canine skin has been grown in a laboratory setting for the first time by researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB. The research team developed a full-thickness dog skin equivalent based on native skin cells. This makes it ...

Win-win in muscle research: faster results and fewer laboratory animals thanks to new method

“The method enables us to ensure that only the muscle fibers actually change their genetic material”

13-Oct-2023 - To study muscle diseases, scientists rely on the mouse as a model organism. Researchers at the University of Basel have now developed a new method that is not only faster and more efficient than conventional ones but also greatly reduces the number of experimental animals needed for studying the ...

Successfully reducing animal testing: The 3Rs principle in fish research

Investigation of cell cultures provides insights into climate change

23-Jun-2023 - According to animal experimentation statistics, fish are the second most commonly used group of animals in research after mice. They play an important role in aquaculture and also serve as model animals in various research areas. "Applying the 3Rs principle means reducing, refining and replacing ...

Caterpillars as a replacement for mammalian models in preclinical research

Research team developed an innovative and unique imaging platform

06-Dec-2022 - Inflammation research is becoming more ethical and economical: caterpillars help to understand gut inflammation and enable the faster and more efficient development of new therapies. Insects, like caterpillars, suffer from the same or related diseases as humans because 75 % of genes associated ...

Stem cells organize themselves into embryoid

Study of mice could enable alternative methods to animal experiments in the medium term

21-Dec-2021 - Researchers at the University of Bonn have developed a method to generate embryo-like cell complexes from the stem cells of mice. The method provides new insights into embryonic development. In the medium term, it might also be suitable for developing tests for substances that could be harmful to ...
