The NOD type of these organisms are used to study IDDM.  The embryological development of these organisms was divided into 26 pre-natal and 2 post-natal stages by Karl Theiler.

These organisms and various products used to study them can be bought at the UC Davis KOMP repository. Commonly used inbred strains of these organisms include BALB/cJ and C57BL/6J.A typical immunodeficient strain of these organisms lacks the ability to produce T-cells and is referred to as ";nude."; Capecchi, Evans, and Smithies won the 2007 Nobel Prize in Medicine for their studies of this organism, and for developing a procedure in which modified stem cells from one strain of this organism are injected into the embryo from another. This organism, whose name is Mus musculus, is commonly used in gene knockout experiments due to its genetic similarity to humans. For 10 points, name this common mammal used in genetic experiments.
