| 000646 | A/J | Level 2 |
| Developed by LC Strong in 1921 from a cross between a Cold Spring Harbor albino and a Bagg albino, the A inbred strain is used widely used in cancer and immunology research. It is highly susceptible to cortisone-induced congenital cleft palate. It has a high incidence of spontaneous lung adenomas, and lung tumors readily develop in response to carcinogens. A high percentage of mammary adenocarcinomas (a large proportion of acinar-type) develop in multiparous females. Rare spontaneous myoepitheliomas arising from myoepithelial cells of various exocrine glands have been observed in The Jackson Laboratory substrains. A/J mice fed an atherogenic diet (1.25% cholesterol, 0.5% cholic acid, and 15% fat) fail to develop atherosclerotic aortic lesions in contrast to several highly susceptible strains of mice (e.g. C57BL/6J, Stock No. 000664; C57L/J, Stock No. 000668, C57BR/c

| 002994 | B6.129X1-Baxtm1Sjk/J | Repository- Live |
| Mice homozygous for the Baxtm1Sjk mutation are viable but display lineage-specific aberrations in cell death. Thymocytes and B cells from homozygous mutant mice display hyperplasia. Ovaries contain unusual atretic follicles with excess granulosa cells while Bax-deficient males are infertile. There is an accumulation of atypical premeiotic germ cells and no mature haploid sperm found in seminiferous tubules. Multinucleated giant cells and dysplastic cells accompany massive cell death. Used in conjunction with strain B6.129-Bak1tm1Thsn/J (see Stock No. 004183), to generate the double knock-out Bak/Bax, a model for demonstrating severe defects in the regulation of apoptosis during development and tissue homeostasis.

| 004088 | B6.Cg-Foxp3sf/J | Repository- Live |
| Scurfy mice develop an X-linked lymphoproliferative disease resulting from defective T cell tolerance. Phenotypes associated with these mice include runting, scaly, crusty skin on the eyelids, ears and tails, dermal thickening, squinted eyes, cachexia, reddening and swelling of the genital papilla, and small testicles that are retained in the abdominal cavity. This disorder, which parallels X-linked autoimmunity-allergic disregulation syndrome (XLAAD) in humans, results in Coombs' test-positive anemia, hypergammaglobulinemia, a small, thin thymus, and lymphohistiocytic proliferation in the skin and lymphoid organs, with splenomegaly, lymphadenomegaly, and hepatomegaly. Foxp3sf/Y males generally die by 16-25 days of age. Transgenic expression of Foxp3 prevents scurfy disease in Foxp3sf/Y mice. Neonatal thymectomy of scurfy males ameliorates disease and increases lifespan; athymic nude Foxp3sf/Y mice do not develop scurfy

| 002188 | B6.129S7-Amhtm1Bhr/J | Repository-Cryopreserved |
| Male mice homozygous for the Amhtm1Bhr mutation have testes that are fully descended and produce functional sperm. They also develop a uterus which interferes with sperm transfer rendering most infertile. The testes develop Leydig cell hyperplasia. Homozygous females are fertile. | ||
| 002283 | B6.Cg-KitW-19H/EiJ | Repository-Cryopreserved |
| This deletion is a dominant mutation causing white spotting on the feet, tail, belly, and occasionally elsewhere. Homozygosity is embryonic lethal. On the C57BL/6 background approximately 60% of heterozygous females have a closed vagina. The ovaries from these heterozygotes are normal and fine for transplantation. On the C57BL/6 background in the presence of the YAKR/J Chromosome (available from Stock No. 007250), KitW-19H heterozygosity results in sex reversed XY females. | ||
| 001271 | B6.RBF-Nek1kat/J | Repository-Cryopreserved |
| The phenotype associated with the Nek1kat-2J allele is more severe than that of the Nek1kat allele. Mice homozygous for Nek1kat-2J all die before one year of age, a third of those that survive weaning die suddenly before 100 days of age, and the reported median survival age is 211 days. Mice homozygous for Nek1kat also have a shortened life expectancy with high pre-weaning mortality and a reported median survival of 286 days, but 22% were found to survive beyond 1 year. Both mutants are runted and have blunted noses with olfactory bulbs that are approximately half the normal size and lack most of the glomerular and external granular layers. In the brain there is dilation of the lateral and third ventricles, cerebral aqueduct and fourth ventricle along with large, fluid-filled cysts in the choroid plexus. Hydrocephalus occurs. Normochromic normocytic anemia is found and is more pronounced in Nek1Kat-2J

| 002784 | B6;129-Dhhtm1Amc/J | Repository-Cryopreserved |
| Mice that are homozygous for the targeted mutation are viable, normal in size and do not display any gross physical or behavioral abnormalities. Homozygous male mice are sterile due to arrested spermatogenesis at the late meiosis, primary spermatocyte stage. Female homozygotes are fertile. No gene product (mRNA) was detectable by semiquantitative RT-PCR analysis of peripheral nerve. Embryonic testis development is impaired. By six weeks of age, the mass of testes from homozygous males is 90% smaller than testes from heterozygous males. Histological examination reveals a diminished number of germ cells and no mature sperm in the testis or epididymis. Peripheral nerves from mutant mice appear flattened with structurally disorganized protective sheaths. The perineural cells, glia and mesenchymal cells, develop defective tight junctions, causing the perineurium to be permeable. This mutant mouse strain may be useful in studies related to male sterility and regulation of peripheral nerve de

New Strains Under DevelopmentThe 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.
- 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
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.
