Commitment to responsible animal research

Advancing life-saving medicine with care, oversight and integrity

A message from Provost Terence R. Flotte

Key fact

Nearly 95 percent of the animals used in research at UMass Chan are mice, rats and zebrafish.

Why this research matters

Research at UMass Chan Medical School has helped advance treatments for some of the most intractable diseases of our time, including HIV, cancer, diabetes, ALS and infectious diseases such as COVID-19.


UMass Chan has led numerous first-in-human clinical trials of novel genetic therapies, including for ALS, Tay-Sachs and Cockayne syndrome.


Every FDA-approved drug requires preclinical research before it can be used on a single patient.

Myths vs. facts

Myth

With modern technology, there is no reason to use animals in research.


Fact

Scientists at UMass Chan and around the world are developing alternatives to laboratory animals in research, but animal models remain the gold standard and the final step often required by the federal government to test therapies for safety and efficacy prior to clinical trials in humans.

Myth

Laboratory animals are mistreated.


Fact

At UMass Chan, we believe that providing compassionate, humane care for laboratory animals is essential—not only because it is the right thing to do, but also because it is fundamental to good science and imperative to meet the demands of high-quality research.

Myth

Large animals are the most commonly used animals in biomedical research.


Fact

Nearly 95 percent of the animals used in research at UMass Chan are mice, rats and zebrafish.

Oversight at every level

Oversight is not a single step—it is a continuous system designed to ensure that research is responsibly conducted and aligned with the highest standards from start to finish.

  • Federal oversight (USDA, NIH)
  • Independent accreditation (AAALAC)
  • IACUC review and approval
  • Veterinary care and monitoring
  • Commitment to the 3Rs (Reduce, Refine, Replace)
