Origin B6/129, fPS1 backcross 12 generations, Nestin-Cre backcross 12 generations Small mice with many gross behavior deficits. Survive up to 3-4 months of age. Premature differentiation of neural progenitor cells reduces cells and neuronal populations. 45% of late-born neurons fail to migrate to their appropriate positions in the superficial cortical layer.

No gross physical or behavioral abnormalities. On PS1 null background mutation results in impaired associative contextual fear conditioning (Wang, 2004). Homozygous mice produce only the mutant gene product. Neurodegeneration by excitotoxin kainate treatment is increased and accelerated. On PS1 null background mutation results in reduced adult neurogenesis in the dentate gyrus (Wang, 2004). Cryopreserved The Jackson Lab: Stock 004193 Guo et al., 1999; Wang, 2004
