Strain Information

Type Mutant Strain; Targeted Mutation;
Mating SystemHomozygote x Homozygote         (Female x Male)
Specieslaboratory mouse
GenerationN20F?+12 (08-JAN-08)
 
Donating Investigator Andrew McMahon,   Harvard University

Description
Mice that are homozygous for the Shhtm2Amc targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This conditional mutant contains two loxP sites flanking exon 2 of the targeted allele. Cre-mediated recombination excises exon 2 and some surrounding intronic sequence, generating a null allele. When the conditional mutant is crossed with a ubiquitously-expressing Cre recombinase carrier to remove Shh activity in the early embryo, the resulting phenotype resembles the Shh null mutation. These conditional mutant mice may be mated to strains expressing Cre recombinase to study the effects of temporal and tissue-specific ablation of the targeted allele. This mutant mouse strain represents a model that may be useful in studies of developmental defects resulting from disruption of Shh-dependent pathways.

When bred to a strain expressing Cre recombinase under the control of a tetracycline-responsive promoter element (see Stock No. 006224,006234, 006244) and a strain expressing a tetracycline-controlled activator protein in the lung and respiratory epithelium (see Stock No. 006225), this mutant mouse strain provides an inducible model for use in studies of hedgehog signalling in respiratory system development.

When bred to a strain with the targeted null allele (Stock No. 003318) 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 expressing Cre recombinase in the nervous system (see Stock No. 003771 for example), this mutant mouse strain may be useful in studies of of hedgehog signalling in cortical interneurons.

Development
The original recombinant allele contained a neomycin resistance gene driven by the mouse phosphoglycerate kinase promoter with flanking loxP sites. The PGK-Neo cassette was removed by Cre-mediated recombination in ES cells to produce the Shh conditional allele. In the Shh conditional allele, exon 2 is flanked by loxP sites. The construct was electroporated into 129 derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts. The resulting chimeric animals were backcrossed to 129X1 mice.

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.
