Description
Multiparous female mice of the WapTag1 lineage develop mammary adenocarcinomas with an average latency of 13 months. The histopathological phenotype is heterogeneous; papillary, ductal, tubular, and sometimes solid phenotypes are observed. Those tumors with a papillary morphology closely resemble human papillary carcinomas. Tumors arise adjacent to morphologically normal mammary epithelium or hyperplastic lesions. Mammary carcinomas are extremely rare in virgin female mice. Male mice, and those female mice that do not develop mammary carcinoma develop undifferentiated soft tissue sarcomas. Multiparous females of the WapTag3 lineage have hyperplastic mammary glands and occasionally develop mammary adenocarcinomas by 6 months of age. At this age, both males and females of this lineage develop osteosarcomas arising from the os petrosum and renal adenocarcinomas.

Development
A 1,600bp mouse whey acidic protein promoter (BglII-KpnI) driving the SV40 early region coding sequences (BglII-BamHI) was microinjected into the male pronucleus of C57BL/6J zygotes. This transgene has been maintained on the C57BL/6J background.

Supply Notes

  • Cryorecovery - Standard.
    Progeny testing is not required.
    The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided, their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders are needed. Animals typically ship between 11 and 14 weeks from the date of your order. If a second cryorecovery is needed in order to provide the minimum number of animals, animals will ship within 25 weeks. IMPORTANT NOTE: The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
