Refers to a line of laboratory mice (genotype Foxn1 nu) that are descended from a mouse in which many years ago occurred a spontaneous mutation which results in (descendants) that:

Do not develop any thymus-derived T cells.

Do not develop hair follicles in their epithelium (skin).

Because this line of laboratory mice will therefore “accept” (i.e., immune system will not attack) a wide variety of transplants (e.g., tumors, etc. from other animals), it is a common research test subject for researchers who want to test the impact of a new pharmaceutical compound on—tumor, and so on. Another aspect making it a commonly chosen test subject is the fact that scientists do not have to shave the mouse in order to measure size of the subcutaneous inserted tumors.
