Rederivation to pathogen-free status via embryo transfer requires submission of 5 males, 10-24 weeks of age and 10 females, 7-12 weeks of age. You will receive all recovered pups after genotyping and health monitoring assays are performed.
Resuscitation and rederivation procedures are performed in pathogen-free barrier facility, and clean surrogate mothers purchased from commercial vendor are used for embryo transfers. You will receive the litters with confirmed genetics and pathogen-free health status.

Weather and Shipping
The welfare of the animals is of utmost importance and as we head into the summer months, inclement weather and excessive heat will delay/prevent shipments of live animals. Be aware that hot temperatures between June and mid-September may negatively impact the ability of couriers to safely ship animals so please plan your live animal orders accordingly.
Provide Your Input on NIH's Proposed Strategic Plan by May 26, 2026.
The NIH is currently seeking input for its next strategic plan, and a major focus of this framework involves the future of animal research. Because these high-level policies directly impact the future of the RRRC and your work, it’s crucial that the scientific community participates. The NIH has provided a short feedback form that only takes a few minutes to complete. Please consider submitting your input. URL: https://grants.nih.gov/
Animal Models and New Approach Methodologies (NAMs)
NAMs are lab (e.g., organoids and iPSCs) or computer-based methods intended to expand our tools for modeling human biology and disease. While this field is rapidly evolving, the need for animal models remains, especially for situations where a complex biological system is necessary. In addition, animal models serve as vital in vivo controls for the validation and verification of emerging NAMs.
