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 .....

000645 A/HeJ
Repository- Live
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 induction of congenital cleft palate by cortisone. It has a high incidence of spontaneous lung adenomas and lung tumors readily develop in response to carcinogens. High percentage of mammary adenocarcinomas (a large proportion 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 small percent (4%) of nonproductive males are hermaphrodites. An additional 17% of nonproductive males have abnormally small testes containing no sperm.

000647 A/WySnJ
Repository- Live
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 induction of congenital cleft palate by cortisone. It has a high incidence of spontaneous lung adenomas and lung tumors readily develop in response to carcinogens. High percentage of mammary adenocarcinomas (a large proportion 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.

Unlike A/J mice, A/WySnJ mice carry a spontaneous mutation in Tnfrsf13c and exhibit a significant loss of mature B cells (Miller, et al., 1991, Lentz et al., 1996, Shulga-Morskaya et al., 2004).

Under Development for Production
Most embryos that are homozygous for this targeted mutation fail between embryonic days 6.5 and 7.0, exhibiting a collapsed extraembryonic region and the absence of organized extraembryonic ectoderm. The embryo proper continues to develop, but fails to initiate gastrulation. Heterozygotes develop a variety of malignant tumors over the course of 10-30 months, including osteosarcoma (63%), lymphoma (15%), lung adenocarcinoma (10%), hepatocellular carcinoma (9%), and fibrosarcoma (9%). A high rate of metastasis to distant sites such as the lung and liver was found. Schwannomas, meningiomas and ependymomas were not detected. RT-PCR analysis and sequencing of the product have shown that a mutant form of mRNA is transcribed and spliced. Immunoblotting fails to detect any full-length or shortened protein products, however. This strain may be useful in studies of embryonic development and cancer.

New Strains Under Development 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.
