The RRRC partners with the MU Animal Modeling Core (AMC) at the University of Missouri to generate new rat models of interest and utility to the research community. If there is a particular rat model that has the potential to be of broad use to the scientific community, please contact us to discuss the possibility of having the RRRC generate this model.

Plan ahead for the holidays
The University of Missouri, home of the RRRC, is closed for business for the holidays at the end of December/beginning of January. Please be aware that we will not be responding to inquiries, providing services or shipping materials from December 22, 2025 through January 2, 2026.
Why Research Resource Identifiers (RRIDs) Are Important
RRIDs are unique identifiers for key biological resources, genetically enigineered animals and reagents like antibodies. Piekniewska et al. document how use of RRIDs improves trackability. Importantly, better citation practices increase research rigor and reproducibility.
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.
In Need of a New Rat Model?
Need a new rat model? The RRRC in conjunction with the MU Animal Modeling Core (AMC) can assist with the generation of transgenic rats, create knock-out and knock-in rats using CRISPR/Cas9 technology and genetically manipulate rat embryonic stem cells to make chimeric animals. Contact us to discuss your rat model needs and how we can help.
