Flt3-ITD homozygous mutant mice develop myeloproliferative disease exhibiting increased myeloid and monocytic cell populations and reduced B and T cell lymphoid cell numbers. This mutant mouse strain may be useful in studies of B cell development, hematopoiesis and myeloproliferative diseases such as chronic myelomonocytic leukemia and Chronic Familial Myelocytic Leukemia-Like Syndrome.

Donating Investigator D. Gary Gilliland,   Brigham and Women's Hospital

Description
These mice carry the human W51 mutation, ITD, internal tandem duplication of amino acids 596 to 602, in the endogenous mouse Flt3 locus, which confers constitutive FLT3 signaling. Mice that are homozygous for the targeted mutation are viable and fertile. The Donating Investigator reports that BALB/c mice carrying this allele are not as viable as mutants on the C57BL/6 background. Although FLT protein levels are comparable to wildtype, increased phospho-Flt3 (p-FLT3) and phospho-Stat5 (pSTAT5) levels are detected by flow cytometric analysis of homozygous bone marrow and splenic cells. Homozygotes exhibit leukocytosis, monocytosis and progressive splenomegaly. Mature myeloid and monocytic populations in homozygotes are increased, with reduced B and T cell populations. B cell development is arrested at the pre-B stage. Heterozygotes have decreased liver size, hemoglobin levels, platelet counts and exhibit a milder maturing myeloid hyperplasia phenotype when compared to homozygotes.

Development
The human W51 mutation (ITD, internal tandem duplication of amino acids 596 to 602) was inserted in-frame into exon 14 and a floxed neo cassette inserted downstream of exon 15. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-Kitl+ derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The donating investigator stated that the resulting chimeric animals were crossed to C57BL/6 mice, and then backcrossed to the same for 9 generations (see SNP note below). Upon arrival at The Jackson Laboratory, the mice were crossed to C57BL/6J at least once 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, all 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/6N genetic background.

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.
