Mutant Mouse Regional Resource Center (MMRRC) at JAX

The Mutant Mouse Regional Resource Center (MMRRC) distributes and cryopreserves scientifically valuable, genetically engineered mouse strains and mouse ES cell lines with potential value for the genetics and biomedical research community.

Researchers at the MMRRC at JAX Repository are developing pluripotent stem cells from selected MMRRC disease model strains using standard derivation techniques and/or iPS technology.  Many studies can be performed in stem cells initially to determine the minimal number of experiments required in live mice.

The MMRRC is a national consortium of breeding and distribution facilities plus an information coordinating center serving together as a NIH-funded repository of spontaneous and induced mutant mouse and cell lines.


The MMRRC is a collaborative effort.  Previously funded by the National Center for Research Resources (grant number RR026296), the MMRRC at JAX is currently supported by the Office of Research Infrastructure Programs/OD (grant number OD010921-03) of the National Institutes of Health.  Please reference these grants in citations acknowledging use of the resource.
