Division of Laboratory Animal Resources
Established in 2005, the Division of Laboratory Animal Resources provides first-rate veterinary services and humane care to all laboratory animals at the Institute.
The Committee of Laboratory Animal Resources is responsible for reviewing all research plans featuring animal experiments, and assessing experimental conditions and animal housing to ensure that experiments are to be carried out humanely and in accordance with The Guide for the Care and Use of Laboratory Animals (National Academies Press, 2011) and The Guideline for Animal Experimentation (NCCHD, 2010). The division follows the Three Rs approach to humane animal experimentation (Replacement, Refinement, and Reduction), which is applied when deciding to use animal models and in the design of humane animal modeling studies.
Our division also oversees the Rodent Health Monitoring Program. As potential pathogens result in data variation and the misinterpretation of results, we supply specific pathogen-free animals to ensure research data integrity and reproducibility. We conduct routine health surveillance and quality control to ensure the suitability of laboratory animals for research models. This program is regularly reviewed by our Committee.
We provide mouse embryo cryopreservation services to researchers at the NCCHD's research institute. Cryopreservation saves the expense and facility space associated with maintaining a live breeding colony of mice that have no immediate use, and preserves viable mouse embryos for future experiments. This method also protects against catastrophic loss of a mouse colony due to accident, breeding decline, disease, or genetic contamination.
In recent years, genetically modified animals such as transgenic and knockout mice have proven useful in research. We offer technical support for the generation, breeding and care of genetically modified animals.
