Stock Number	Strain Name   Strain Description	Standard Supply
004456	NONcNZO10/LtJ	Level 2
	Onset of hyperglycemia occurs between 10-12 on a 10-11% fat (wt/wt) chow diet with greater than 85% diabetic by 18 weeks. Males exhibit increased serum triglycerides, moderate to severe liver steatosis and pancreatic islet atrophy similar to NZO/HlLt males. Serum insulin and leptin values are significantly lower than in NZO/HlLt, and are only moderately elevated above those recorded in NON/ShiLtJ males. Unlike the very obese NZO/HlLt mice, NONcNZO10/LtJ mice do not exhibit hyperphagia or hypercorticism and are much easier to breed. Although NONcNZO10/LtJ males develop only a moderate level of obesity compared to NZO/HlLt males, the interaction with known diabetogenic QTL from the NON/ShiLtJ strain produce an earlier onset and higher prevalence of chronic hyperglycemia than observed in NZO/HlLt males. NONcNZO10/LtJ is differentially sensitive to adverse hepatic side effects of thiazolidinediones and may be useful for pharmac ogenetic analysis. This strain represents a model of polyg .....

003923	B6.HRS(BKS)-Cpefat/J	Repository- Live
	Mice homozygous for the fat spontaneous mutation (Cpefat) on a C57BL/6J genetic background (N10) become noticeably obese by 14-15 weeks of age. There is also some sexual dimorphism; female homozygous mutant mice develop obesity at a later age than males. Cpefat mice actually weigh less than wildtype controls prior to weaning age. Homozygous mutant mice develop a diabetic phenotype characterized by hyperglycemia and insulin resistance. Cpefat mice appear healthier on the C57BL/6J genetic background, avoiding the hereditary hydronephrosis present in C57BLKS/J and a lower incidence of malocclusion.
002106	KK/HlJ	Repository- Live
	KK/HlJ male mice exhibit diabetic symptoms that includes hyperglycemia, hyperinsulinemia, and insulin resistance. This strains serves as a model of noninsulin dependent diabetes mellitus, type 2.
005067	NZL/LtJ	Repository- Live
	Male NZL/LtJ mice develop juvenile-onset obesity and maturity-onset hyperglycemia (McInerney MF, et al., 2004). Over 90% of males exhibit hyperglycemia of >250 mg/dl by 20 weeks of age. Body weight in males increases to 55 gm by 16 weeks of age. The diabetic phenotype is very similar to that of NZO/HlLt J (Stock No. 002105) mice. An advantage of NZL/LtJ over NZO/HlLtJ as a diabetes model, in addition to the higher disease incidence, is that mice of this strain breed well, whereas NZO/HlLt mice breed very poorly. This strain carries the wildtype Igh-6 allele from the NZO/HlLtJ strain.
002391	BKSChpLt.HRS-Cpefat/J	Repository-Cryopreserved
	Mice homozygous for the fat spontaneous mutation (Cpefat) on a C57BLKS/J genetic background (N10) have a diabetes phenotype that is primarily restricted to males and is more severe than what is seen on the original HRS/J or C57BLKS/J (N5) genetic backgrounds. At weaning both males and female homozygous mutant mice were significantly lighter than wildtype or heterozygous littermates. Obesity develops between 6 and 8 weeks of age and mutant mice can be distinguished from wildtype littermates between 8 and 12 weeks of age. By 18 weeks fat mutant mice will reach 45-55 g and may reach 60-70 g by 6 months of age. Thus, the obesity is thus slower to develop than in the obese (Lepob) and diabetes (Leprdb) mutant mice. The excess adiposity is distributed throughout the body's fat stores, in contrast to the largely axial and inguinal fat deposition of the obese and diabetes mutant mice. Hyperinsulinemia is severe by 4 weeks of age and contin ..... For more information please see the full descriiption on the strain data sheet

	002105	NZO/HlLtJ	On Hold
	NZO mice of both sexes exhibit high birth weights and are significantly heavier at weaning age, Severe obesity (including both visceral and subcuatneous fat depots) develops even when mice are maintained on a standard diet containing 4.5% fat. Both males and females of the NZO/Hl substrain exhibit impaired glucose tolerance (IGT), but subsequent type 2 maturity onset (NIDDM) diabetes development is limited to males, with a phenotype penetrance of 50% or less. NZO/Hl mice also show anti-insulin receptor antibodies, a defect in leptin transport, and hypertension. The genetic lesion appears to be within the islets of Langerhans as transfer of pancreatic islets from normal mice returns body weights and blood glucose levels to within normal range. Ovarian granulosa cell tumors, lymphomas, duodenal, and lung tumors have also been noted to occur in NZO mice at an elevated frequency. F1 hybrids of NON/ShiLt and NZO/Hl provide a new model of obesity-induced diabetes. Male (NON/ShiLt x NZO/Hl)F1 ..... For more information please see the full description on the strain data sheet

New Strains Under Development

• Receive periodic updates on the status of the colony UNDER DEVELOPMENT
• Obtain advance notification of strain availability and opportunity to order prior to the strain being published as available
• Provide input affecting speed and quantity of availability

The Jackson Laboratory serves as a worldwide distributor and national repository for common and rare strains of inbred mice and mice carrying spontaneous mutations or induced mutations (i.e., transgenic, targeted/"knockout", or chemically induced mutations). At any one time, we have over 100 strains at various stages of development and colony expansion. Strains "Under Development" fall into two categories depending on the anticipated demand from the scientific community.

1. Strains that will be made available from a live distribution colony at The Jackson Laboratory.
   These strains are designated as: "Under Development for Distribution Colony"
2. Strains that will be made available through the Cryopreservation Repository.
   These strains are designated as: "Under Development for Cryopreservation Repository"

It is VERY IMPORTANT that you register interest in strains Under Development. The anticipated demand for a strain enables us to determine effectively the distribution plan for each strain Under Development. Registering interest also provides benefits to you (including advance notification of pending availability). Whether a strain is made available from a live colony OR from our cryopreservation repository, you may want to consider the option of Dedicated Supply. To learn more about Dedicated Supply, go to Services.
