2 If an assessment has not been performed by the MMRRC (as indicated by "NO"), investigators may request specific testing for a fee. Requests should be submitted directly to the MMRRC Distribution Center assigned to the management, archiving, and distribution of the strain. A full listing of available testing and analytical services is available at https://www.mmrrc.org/about/services.php.

Tg(Sox10-cre/ERT2)1Sout
Name: transgene insertion 1, E Southard-Smith
Type: Transgene
Species: Multi-species
Chromosome: unknown
Alteration at locus: Transgenic
Genetic Alterations
Using the BAC containing Sox10 regulatory regions, a Cre recombinase coding region fused with a mutated ligand-binding domain of the human estrogen receptor (ERT2) was inserted directly downstream of the transcription initiation site. LoxP sites in the BAC flanking arms were removed prior to microinjection. The Sox10 regulatory regions drive neural crest-specific expression of CreERT2 recombinase.

Phenotype
Tg(Sox10-CreERT2)1Sout mice do not exhibit an overt pathological or developmental phenotype and are viable and fertile; rather, the strain’s defining “phenotype” is its highly specific, inducible Cre activity pattern.

Conditional Phenotype: When crossed to Cre reporter lines and induced with tamoxifen, Tg(Sox10-CreERT2)1Sout shows tight temporal and spatial control of recombination, recapitulating endogenous Sox10 expression.

Upon tamoxifen induction, the Cre/ERT2 protein translocates specifically into the nuclei of Sox10-expressing enteric glial cells, peaking at 18–24 hours post-gavage. By 24 hours nuclear localization begins to decline, and by 48 hours Cre/ERT2 returns to a diffuse cytoplasmic pattern. Consistent expression of Sox10 in non-neural crest derived glandular epithelium, including salivary, mammary, and urethral glands of adult mice was also observed.

The Sox10-cre/ERT2 transgenic line is a verified tool that will enable refined temporal and cell-type specific lineage analysis of neural crest derivatives as well as glandular tissues that rely on Sox10 for proper development and function.

Strain Development
The Sox10-cre/ERT2 BAC targeting constructs were generated via in vitro modification of the Bacterial Artificial Chromosome 28O11 so that the Cre coding sequence was inserted in frame with Sox10 ATG.
The targeting construct does not remove any regions of the Sox10 locus upon integration and thus maintains all Sox10 exons, introns, and regulatory regions.

Successful homologous recombination was first identified by screening for tetracycline resistant colonies, confirmed by PCR of individual clones, and verified by sequencing across integration junctions. Removal of the tetracycline cassette was achieved by L-arabinose induction of Flp recombinase, and restoration of tetracycline sensitivity was confirmed by replica plating.

The Sox10-cre/ERT2 BAC DNAs were prepared and injected separately into fertilized (C57BL/6 X SJL) F2 mouse egg. Genomic DNA was isolated from postnatal day 10 (P10) founder tail snips and screened for detection of the BAC transgene using PCR amplification. Six transgene positive founders were obtained for the Sox10-cre/ERT2 construct that were subsequently bred out to establish five lines (Lines A, B, C, D, and E). Sox10-cre/ERT2 lines A and B carried all expected internal simple tandem repeat markers within the BAC and exhibited comparable expression patterns consistent with labeling of neural crest lineages. Lines were subsequently maintained by backcrosses to C3HeB/FeJ stocks (RRID:IMSR_JAX:000658) for more than 20 generations.

Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain's tissue samples taken when archived by or ordered from the assigned MMRRC Center.

Order Information

Limited quantities of breeder mice (up to 2 males and 2 females or 4 mice) per investigator per month are available from a live colony, usually available to ship in under 12 weeks. Larger quantities may be available, please contact the distributing center directly at mmrrc@missouri.edu for more details.

Cryopreserved material may be available upon request, please inquire to mmrrc@missouri.edu for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The submitter or their institution limits the distribution to non-profit institutions only.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
