Donating Investigator Dr. Janet Rossant, The Hospital for Sick Children
Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Homozygotes have an embryonic lethal phenotype, failing to develop past approximately 9.5dpc due to the lack of hematopoietic and endothelial cells. Fluorescence in heterozygous embryos is detected as early as the primitive streak stage and mimics the endogenous gene expression pattern.
A targeting vector containing eGFP, and a loxP site flanked PGK-NEO cassette, was used to disrupt exon 1. The construct was electroporated into 129 derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to Cre deleter strain to remove the floxed selection cassette. The mice were then crossed to ICR mice. Upon arrival at The Jackson Laboratory, the mice were crossed to ICR/HaJ mice (Stock No. 009122) at least once to establish the colony.

|Strain of Origin||(129X1/SvJ x 129S1/Sv)F1-Kitl<+>|
|Site of Expression||GFP is expressed in hematopoietic and endothelial cells as early as the primitive streak stage.|
|Gene Symbol and Name||Kdr, kinase insert domain protein receptor|
|Gene Common Name(s)||CD309; FLK1; Flk-1; Flk1; VEGF receptor-2; VEGFR; VEGFR-2; VEGFR2; fetal liver kinase 1; vascular endothelial growth factor receptor- 2;|
|Molecular Note||An in-frame EGFP cDNA gene and a floxed PGK-neomycin resistance cassette replaced the translated portion of the first coding exon and the proximal part of the next intron, and placed EGFP under the transcriptional control of the endogenous promoter. The floxed PGK-neomycin promoter was subsequently removed by crossing to a cre-deleter strain. [MGI Ref ID J:109435]|
