Detailed Description

These transgenic mice express Cre recombinase under the control of the mouse SRY-box containing gene 2 promoter. The transgene integrated into an intron of Edil3 (EGF-like repeats and discoidin I-like domains 3). The insertion results in a functional knock-out of Edil3 in homozygous mice. Founder line 1 has a copy number of 2-5. Mice hemizygous for the Sox2Cre transgene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When these transgenic mice are bred with mice containing loxP-flanked sequences, Cre-mediated recombination will result in deletion of the floxed sequences in Cre-expressing tissues in the offspring. Specifically, Cre recombinase activity is detected in the epiblast cells at embryonic day 6.5, with little or no activity in other cells at gastrulation. Some activity is also detected in extra embryonic derivatives of the epiblast, the yolk sac mesoderm and amnion. No Cre recombinase activity is detected in primitive endoderm derived tissues, visceral endoderm. The phenotype of homozygous mice has not been characterized to date (April 2011). These Sox2Cre transgenic may be useful for generating epiblast-derived specific conditional mutations. Transgene expression is active in the female germline. Offspring arising from a hemizygous transgenic female will exhibit Cre recombinase activity, regardless of genotype. This maternal inheritance effect, due to female germline expression of the transgene, can provide a rapid and efficient breeding mechanism for generating null animals.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.

Development

The Sox2Cre transgene was designed with 12.5 kb of upstream regulatory sequence from the mouse Sox2 locus (SRY-box containing gene 2), a chicken β-actin intron, a Cre recombinase gene, and a rabbit β-globin poly(A) sequence. This transgene was introduced into B6CBAF1 donor eggs. The resulting founder animals were initially crossed to C57BL/6 mice, and then crossed to outbred Swiss Webster mice. The transgene integrated into an intron of Edil3 (EGF-like repeats and discoidin I-like domains 3) on chromosome 13. Founder line 1 has a copy number of 2-5. The donating investigator reported that the mice were backcrossed to C57BL/6 for 11 generations before being sent to The Jackson Laboratory Repository (as Stock No. 008454). There, some mice were subsequently backcrossed to C57BL/6NJ inbred mice (Stock No. 005304) for several generations using a marker-assisted, speed congenic approach to generate this C57BL/6N-congenic strain as Stock No. 014094.

Allele Name	transgene insertion 1, Andrew P McMahon
Allele Type	Transgenic (Recombinase-expressing, Null/Knockout)
Allele Synonym(s)	Sox2::Cre; Sox2Cre; Sox2-cre; Sox2-Cre^tg; Tg(Sox2-cre)1Amc
Gene Symbol and Name	Edil3, EGF-like repeats and discoidin I-like domains 3
Gene Synonym(s)
Promoter	Sox2, SRY (sex determining region Y)-box 2, mouse, laboratory
Expressed Gene	cre, cre recombinase, bacteriophage P1
Site of Expression	epiblast cells at embryonic day 6.5, with little or no activity in other cells at gastrulation; some activity is also detected in extra embryonic derivatives of the epi-blast, the yolk sac mesoderm and amnion; no activity is detected in primitive endoderm derived tissues, visceral endoderm
Strain of Origin	(C57BL/6 x CBA)F1
Chromosome	13
General Note	Hemizygous transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities.
Molecular Note	This transgene expresses Cre recombinase under the control of a mouse Sox2 promoter contained in 12.5 kb of upstream DNA. Expression of this transgene is sex-dependent, with increased efficiency when passed through the female germline. When the transgene is passed through the male germline, cre activity is observed in epiblast cells as early as E6.5 of only those embryos that inherit the transgene and no expression is detected in extraembryonic tissue. When the transgene is passed through the female germline, cre activity is observed throughout the embryo (including the yolk sac) in all early embryos regardless of whether or not they inherit the transgene. Line 1 inserted into an intron of the gene at 89311726-89311727 (Build GRCm38/mm10) resulting in a functional knockout of the gene. Founder line 1 has a copy number of 2-5.

Breeding Considerations

Transgenic mice were bred to C57BL/6NJ inbred mice (Stock No. 005304) for many generations to establish this congenic strain. When maintaining the live congenic colony, hemizygous mice may be bred with wildtype (noncarrier) siblings or to C57BL/6NJ inbred mice (Stock No. 005304). The phenotype of homozygous mice has not been characterized to date (April 2011). Of note, transgene expression is active in the female germline. Offspring arising from a hemizygous transgenic female will exhibit Cre recombinase activity, regardless of phenotype.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
