Generation DefinitionsDonating Investigator Elizabeth Simpson, University of British Columbia Description
These Ple90-EGFP;mEMS1899 mice have the Ple90-EGFP transgene targeted as a single copy "knockin" into the upstream region of hypoxanthine guanine phosphoribosyl transferase (Hprt) locus on the X chromosome. Heterozygous females and hemizygous males are viable and fertile, with the promoter/regulatory regions of the human glial fibrillary acidic protein (GFAP) gene directing expression of enhanced green fluorescent protein (EGFP). These Ple90-EGFP;mEMS1899 mice may be useful in studying GFAP-expressing cells in the brain and diseases affecting the brain.For Ple90-EGFP;mEMS1899 expression information, see The Pleiades Promoter Project website (Ple90 Promoter (pEMS1377)).
The donating investigator reports:
The expression pattern of the Ple90 MiniPromoter is quite similar to the expression of Ple88 (GFAP-A; see Stock No. 008706); with broad expression in glial cellular profiles throughout the brain and spinal cord. Numerous astroglial profiles are seen in the cortical grey and white matter and in the cerebellum the full extent of Bergmann glial processes are highlighted with anti-EGFP immunocytochemistry. EGFP-immunoreactivity is most prominent in the cell bodies across all regions, with a subpopulation of cells showing a halo of process staining.These mice were created and deposited by The Pleiades Promoter Project (Centre for Molecular Medicine and Therapeutics, University of British Columbia).
Development
The Ple90-EGFP transgene (pEMS1377) was designed with the 1433 bp Ple90 minipromoter (GFAP-C; derived from a putative upstream regulatory region and a portion of the promoter of the human glial fibrillary acidic protein (GFAP) gene) upstream of a minimal F5 mutant-frt site, an enhanced green fluorescent protein (with mutated TAA->TTA stop), a nuclear localization signal, a second minimal frt site, an SV40 early polyA signal, and a human HPRT complementary sequence (containing exon1, intron1, exon2, and part of intron2). This construct was targeted as a single copy knockin to the Hprtb-m3 mutant locus on the X chromosome via electroporation into mEMS1204 embryonic stem cells (generated from F1 generation male pups born of C57BL/6-congenic females homozygous for a Hprtb-m3 mutation [originally derived from 129P2/OlaHsd-derived E14TG2a embryonic stem cells] X 129S-Gt(ROSA)26Sortm1Sor heterozygous males (see Stock No. 002171 and 003310, respectively)). Correctly targeted embryonic stem cells were microinjected into recipient mice cells. The resulting chimeric males (founder line mEMS1899) were bred to B6(Cg)-Tyrc-2J/J females (B6-albino; Stock No. 000058) to establish the mutant colony. These Ple90-EGFP;mEMS1899 mutant mice were bred with C57BL/6J wildtype mice for five generations. Black mice without the Gt(ROSA)26Sortm1Sor or Tyrc-2J mutations were sent to The Jackson Laboratory. Upon arrival, Ple90-EGFP;mEMS1899 mutant mice were used to cryopreserve sperm. When rederiving a live colony, sperm will be used along with oocytes from C57BL/6J inbred mice (Stock No. 000664) to generate obligate heterozygous females, and these females will be bred at least one generation to C57BL/6J inbred mice to establish the colony.For more information, see The Pleiades Promoter Project website (Ple90 Promoter (pEMS1377)).

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.Ordering Information
