Detailed Description

Mice homozygous for the Shh^tm1Amc targeted mutation display early defects in the establishment and maintenance of midline structures. These defects result from the critical role the Sonic hedgehog (Shh) gene plays in the patterning of vertebrate embryonic tissues, including the brain and spinal cord, the axial skeleton and the limbs. Defects are also observed in all tissues, confirming the proposed role of SHH proteins as an extracellular signal required for the tissue-organizing properties of several vertebrate patterning centers.

When bred to a strain with loxP sites inserted into the same targeted allele (Stock No. 004293) and a strain expressing Cre recombinase in the skin and dental epithelium (Stock No. 004782), this mutant mouse strain may be useful in studies of hedgehog signalling and cell proliferation in the dental epithelium.

When bred to a strain with loxP sites inserted into the same targeted allele (Stock No. 004293) and a strain expressing Cre recombinase in the mesonephric duct and its developmental derivatives (Stock No. 004692), this mutant mouse strain may be useful in studies of hedgehog signaling and cell proliferation/differentiation in mesenchymal cells of the kidney.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We 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.

Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

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.
