Non-obese diabetic (NOD) mice are isolated from the cataract-susceptible subline of inbred strain Jcl:ICR mice at the sixth generation. In the 20th generation of inbreeding, 60% - 80% of female and 20% - 30% of male NOD mice spontaneously developed insulin-dependent diabetes mellitus, and the risk of diabetes mellitus in NOD mice raised in an aseptic environment was significantly higher than that in a normal environment.
