Detailed Description

These S1pr1^loxP/loxP mice possess loxP sites flanking exon 2 of the sphingosine-1-phosphate receptor 1 (S1pr1) gene. S1PR1 is a G protein-coupled receptor for lysophospholipid sphingosine-1-phosphate (S1P) and is highly expressed in endothelial cells. S1PR1 is essential for vascular maturation during embryonic development and is also involved in cell survival, migration, adhesion, and proliferation. This receptor plays a role in the regulation of innate and adaptive immune responses by controlling lymphocyte egress from the thymus, spleen, bone marrow, and lymph nodes. It has also been implicated in the regulation of vascular function. Mice that are homozygous for this allele are viable and fertile. When these mutant mice are bred to mice that express Cre recombinase, resulting offspring will have exon 2 deleted in cre-expressing tissues.

For example, when crossed to B6.Cg-Tg(Tek-cre)1Ywa/J (Stock No. 008863)
Mice expressing Cre recombinase in vascular endothelial cells during embryogenesis and adulthood, the resulting offspring die by E14.5 due to muscle defects including heart, vascular smooth muscle, and skeletal muscle defects.

Development

A targeting vector was designed to insert a single loxP site upstream of exon 2, and a loxP-flanked neomycin resistance (neo) cassette downstream of exon 2 of the sphingosine-1-phosphate receptor 1 (S1pr1) gene. The construct was electroporated into 129S6/SvEvTac-derived TC1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts and resulting chimeric males were bred with C57BL/6NCrl females. Offspring, heterozygous for this S1pr1^loxP allele, were bred with B6.FVB-Tg(EIIa-cre)C5379Lmgd/J transgenic mice (Stock No. 003724) to delete the neo cassette. Resulting mice contained multiple gene rearrangments; intact floxed-exon 2, intact floxed-neo cassette, or excision of both exon 2 and the neo cassette. Progeny, containing only the floxed-exon 2, were crossed to remove the Cre-expressing transgene. The donating investigator reported that these mice were bred to C57BL/6NCrl mice for at least 7 generations (see SNP note below). Upon arrival, mice were bred to C57BL/6NJ inbred mice (Stock No. 005304) for at least one generation to establish the colony.

A 32 SNP (single nucleotide polymorphism) panel analysis, with 27 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. While the 27 markers throughout the genome suggested a C57BL/6 genetic background, 3 of 5 markers that determine C57BL/6J from C57BL/6N were found to be segregating. These data suggest the mice sent to The Jackson Laboratory Repository were on a C57BL/6J genetic background.

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.

Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.

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.
