RNU Nude Rat Details
The NIH nude rat was developed in 1979–1980 through a series of matings involving 8 inbred rat strains. To Charles River from the National Institutes of Health in 2001. This athymic nude rat is T-cell deficient and shows depleted cell populations in thymus-dependent areas of peripheral lymphoid organs.
The control model for the RNU nude rat is the RNU Heterozygous Rat (RNU+).
