Animal Testing Alternatives Progress

Advances in 3D tissue models, organ-on-chip technology, and computational methods are creating viable alternatives to animal testing across multiple research domains.

Key Facts

Approximately 115 million animals are used in research globally each year
Organ-on-chip devices replicate human tissue function more accurately than animal models for some applications
3D organoids grown from human cells can model disease processes without animal subjects
Computational toxicology uses molecular structure to predict chemical hazards
The US and EU have committed to developing animal-free safety testing pathways
Some pharmaceutical companies have eliminated certain categories of animal testing voluntarily

Welfare Considerations

Animals used in safety testing experience procedures ranging from mild observation to severe chemical exposure, surgery, and death. Chronic toxicity studies subject animals to months of exposure to potentially harmful substances. The development of more predictive, human-relevant alternatives not only reduces animal suffering but often produces more accurate safety data — a dual benefit. The pace of adoption of validated alternatives remains slower than the science would support, due to regulatory inertia.

What You Can Do

Support the development and regulatory acceptance of animal-free testing methods
Purchase from cosmetic brands that have eliminated animal testing
Advocate for regulatory agencies to fast-track validation of alternative methods
Donate to research funds developing human-relevant disease and safety models
Support legislative mandates for agencies to adopt validated alternatives
Raise awareness about the availability and scientific validity of alternatives
