000659 C3H/HeJ
Level 1
C3H/HeJ mice are used as a general purpose strain in a wide variety of research areas including cancer, immunology and inflammation, sensorineural, and cardiovascular biology. C3H/HeJ mice and all other Jackson substrains are homozygous for the retinal degeneration 1 mutation (Pde6brd1), which causes blindness by weaning age. There is also a high incidence of hepatomas in C3H mice (reportedly 72-91% in males at 14 months, 59% in virgin females, 30-38% in breeding females). Despite the lack of exogenous mouse mammary tumor virus (MMTV), virgin and breeding females may still develop some mammary tumors later in life. C3H/HeJ 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. 00066 .....

000635 C3H/HeOuJ
Level 2
C3H/HeOuJ mice are used as a general purpose strain in a wide variety of research areas including cancer and sensorineural, research. C3H/HeOuJ mice and all other C3H substrains at The Jackson Laboratory are homozygous for the retinal degeneration 1 mutation (Pde6brd1), causing blindness by weaning age. There is also a high incidence of hepatomas in C3H mice (reportedly 72-91% in males at 14 months, 59% in virgin females, 30-38% in breeding females). Despite the lack of exogenous mouse mammary tumor virus (MMTV), virgin and breeding females may still develop some mammary tumors later in life.
000654 CBA/CaJ
Level 2
The CBA inbred strain was initially bred for longevity and a low incidence of spontaneous mammary tumors (compared with C3H). Burdette and Strong reported that CBA mice were comparatively susceptible to tumor induction after a single subcutaneous injection of methylcholanthrene. The tumor types identified in this early work in CBA mice included spindle cell sarcoma, rhabdomyosarcoma, and epidermoid carcinoma. Strong and Smith reported finding benign hepatomas in aging CBA mice. Several groups confirmed this finding, and the majority of studies found a higher frequency of spontaneous hepatomas in males than in females.

CBA/Ca mice are commonly used for leukemogenesis research because this strain has a low spontaneous incidence of leukemia but has a relatively high inducibility of myeloid leukemia in response to benzene and radiation exposure. Multiple reports using CBA, its F1 hybrids, and other strains, have indicated that deletions in a specific segment of chromosome 2 are linked .....

001143 CBA/CaGnLeJ
Repository- Live
000655 CBA/CaH-T(14;15)6Ca/J
Repository- Live
This strain carries the T(14;15)6Ca translocation which results in nondisjunction at a rate of 4.4% in males and 22.2% in females. CBA/CaH-T6 mice have been used in tandem with the CBA/H strain in foreign body tumorigenesis studies in which the T6 chromosome was used as a marker to distinguish donor cells from host.
002662 C.Cg-Fechm1Pas/J
Repository-Cryopreserved
Homozygous mutants are recognizable by the intense yellow color of their sera, gross bilirubinemia, and, especially in albino mice, jaundice. Photosensitivity is evidenced by the appearance of inflammatory skin lesions, often becoming ulcerous, under standard mouseroom conditions (fluorescent light). Mutants do not differ from their normal littermates in body size or weight, nor are they retarded in growth. They exhibit hepatomegaly and splenomegaly, leading to enlarged abdomens after several months of age. Although mutants are not anemic at one month old, normocytic anemia develops with age.

008247B6.Cg-Tg(Ela1-TAg*)289Mjt/J
Under Development for Production
Hemizygous T1-147 transgenic mice (harboring the E1-T147 transgene) are viable and fertile, with high-level expression of an N-terminal, truncated (1-147 amino acid), and mutant (does not express the small t antigen) form of simian virus 40 large T antigen (TAg) directed to pancreatic acinar cells by the rat elastase 1 (Ela1 or E1) upstream control region. Hemizygous T1-147 transgenic mice exhibit pancreatic dysplasia in the embryonic pancreas, with cancer progression after birth to primary pancreatic acinar cell tumor formation (100% penetrance). These mice have microadenomas and acinar cell carcinomas present as early as 10 weeks of age, and become moribund or show clear evidence of abdominal distention around 20-30 weeks of age. T1-147 transgenic mice with large tumors develop metastatic disease to the liver and mesenteric lymph nodes. The donating investigator reports that the cancer phenotype of these T1-147 transgenic mice is identical to that of their similar T1-127 trans .....

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.
