| 003658 | STOCK Tg(TIE2GFP)287Sato/J | Level 4 |
| This strain expresses Green Fluorescent Protein (GFP) under the direction of the endothelial-specific receptor tyrosine kinase (Tek, formerly, Tie2) promoter. Endothelial cells expressing GFP can be visualized via fluorescent microscopy or purified by FACS. | ||
| 006137 | B6.Cg-Tg(Cdh5-cre)7Mlia/J | Repository- Live |
| Hemizygotes are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. In the differentiated endothelium transgene expression is observed as early as E7.5 and progresses to almost full penetrance by E14.5. In adult mice, uniform cre expression is observed in the endothelium of developing and quiescent vessels of all organs examined, as well as within a subset of hematopoietic cells. When bred with any mouse containing a loxP-flanked sequence of interest, Cre-mediated recombination will result in deletion of the flanked genome. These mice may be useful in studies of the cardiovascular system, including angiogenesis, and endothelial and hematopoietic cell lineages. | ||
| 004659 | B6.Cg-Tg(TIE2GFP)287Sato/1J | Repository- Live |
| This strain expresses Green Fluorescent Protein (GFP) under the direction of the endothelial-specific receptor tyrosine kinase (Tek, formerly, Tie2) promoter. Endothelial cells expressing GFP can be visualized via fluorescent microscopy or purified by FACS. 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. | ||
| 006044 | B6;129S7-Ephb4tm1And/J | Repository- Live |
| Mice homozygous for this targeted mutation show growth retardation and lack of blood flow by embryonic day 9.5-10 (E9.5-10), with lethality occurring around this time. Expression of lacZ occurs exclusively in embryonic vascular endothelial cells and is preferentially expressed on veins. Homozygous embryos show defective angiogenic remodeling at the capillary plexus stage in both yolk sac and head. Arrested cardiac morphogenesis and defective myocardial trabecular extensions are also observed. Heterozygous mice are viable, fertile, exhibit no behavioral defects, and have identical lacZ expression patterns. These mutant mice may be useful in studying the cellular and molecular mechanisms underlying vasculogenesis and angiogenesis, the topography of neovascularization, and adult neovascularization, including tumor angiogenesis. The developmental abnormalities in homozygous mice closely resemble those observed for mutant mice bearing a lacZ-expressing null mutation

| 002856 | FVB/N-Tg(TIE2-lacZ)182Sato/J | Repository- Live |
| Transgenic mice carry a beta-galactosidase reporter gene under the control of the murine Tek (Tie2) promoter. LacZ is expressed specifically in vascular endothelial cells in embryonic and adult mice. The transgenic line may be useful when crossed with tumor producing strains and the transgene used to visualize neovascularization during tumorigenesis. | ||
| 006770 | STOCK Rag1tm1Mom Tg(TIE2GFP)287Sato/J | Repository- Live |
| To generate this double mutant strain, B6.Cg-Tg(TIE2GFP)287Sato/1J (Stock No. 004659) was crossed to C.129S7(B6)-Rag1tm1Mom/J (Stock No. 003145). This mutant mouse strain may be useful in studies examining angiogenesis in transplanted tissues. 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. This is the case for the strain above. It should be noted that the phenotype could vary from that originally described for each single mutant. We will modify the strain description if necessary as published results become available. | ||
| 005493 | STOCK Tg(Tek-rtTA,TRE-lacZ)1425Tpr/J | Repository- Live |
| Hemizygous transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice harbor co-injected transgenic constructs. The reverse tetracycline-controlled transactivator (rtTA) protein is expressed under the direction of the endothelial-specific receptor tyrosine kinase enhancer/promoter (Tek). The second transgenic construct expresses a nuclear-localizing beta-galactosidase gene (lacZ) under the control of a tetracycline-responsive element (TRE). In the presence of tetracycline or a tetracycline analog (such as doxycycline), selective expression of lacZ is observed in the nuclei of vascular endothelium in a wide variety of tissues (aorta, heart, brain, lung, kidney, liver, spleen, uterus, prostate, stomach, skeletal muscle, large and small intestine). Expression is observed as early as embryonic day 9.5. In the absence of tetracycline, some lacZ expression occurs in the smaller branches of

| 006039 | B6.129S7-Efnb2tm1And/J | Repository-Cryopreserved |
| Mice homozygous for this targeted mutation show growth retardation and enlargement of the heart at embryonic day 10 (E10), with 100% lethality occurring around E11. Reporter protein expression patterns are consistent with arterial, but not venous, expression of the endogenous gene; prominent lacZ signal is observed in hindbrain and somites, with lower levels in aorta and heart as early as E8.25. Expression in the yolk sac was first detected at E8.5, and is also observed in nephrogenic mesoderm and branchial arches. Homozygous embryos show defective angiogenic remodeling at the capillary plexus stage in both yolk sac and head. Endothelial vessel support cell differentiation of the yolk sac is also defective. Homozygotes lack myocardial trabecular extensions, and capillary ingrowth into the neural tube does not occur. Heterozygous mice are viable, fertile, exhibit no behavioral defects, and have identical lacZ expression patterns. These mutant mice may be useful in studying

| 003266 | B6;129S7-Epas1tm1Rus/J | Repository-Cryopreserved |
| Mice homozygous for the Epas1tm1Rus targeted mutation develop normally until embryonic day 11.5. Beginning at embryonic day 12.5 the ratio of homozygous embryos begins to decline and by day 16.5 there are no viable mutant embryos. Overall morphological development, including the circulatory system, is normal. Of particular interest however, is a pronounced bradycardia in homozygous mutant mice. Catecholamine levels in homozygous mutant mice are also significantly lower than wildtype controls. Administration of the catecholamine precursor DOPS to pregnant females rescues approximately 40% of mutant embryos. Embryos that survive to birth appear runted, fail to nurse, and die within 24 hours of birth. These results suggest a pivotal role of EPAS1 in catecholamine homeostasis. Heterozygous mice from this strain contain a modified lacZ gene in the targeting construct. This characteristic makes this strain useful as a marker for endothelial cells. | ||
| 005707 | STOCK Rag1tm1Mom Tg(TIE2-lacZ)182Sato/J | Repository-Cryopreserved |
| Mice homozygous for both the targeted mutation and the transgene are viable and fertile. The transgene beta-galactosidase is well expressed, reflects endogenous Tek/Tie2 activity, and is specific to the vascular endothelium. Mice homozygous for the Rag1 mutation are immunodeficient as they lack mature B and T lymphocytes. This double mutant mouse may be useful in studies of cancer, tumor-related angiogenesis, and as a recipient of xenografted tumors. | ||
