| Homozygous mice are viable and fertile, with a loxP-flanked DNA STOP sequence preventing expression of the downstream lacZ gene. When crossed with a cre transgenic strain, the STOP sequence is removed and lacZ is expressed in cells/tissues where cre is expressed. These mutant mice may be used as a Cre-reporter strain; to test the tissue/cellular expression pattern of cre transgenic mice. | ||

| MADM-GG mice are viable with no gross behavioral or observable abnormalities. Regardless of Cre-recombination, these mice express EGFP as their N- and C-terminal coding sequences are interrupted by the beta-actin intron in-frame. High EGFP expression in every cell can be visualized in vivo and in fixed samples. These mutant mice are a control EGFP-expressing strain for use with MADM (mosaic analysis with double markers) mice (see Stock No. 006041 [MADM-GR (EGFP/Dsred2)] and Stock No. 006067 [MADM-RG (Dsred2/EGFP)]). Using the MADM system, a researcher can generate genetic mosaics in which an individual organism contains somatic cells of different genotypes. This allows the researcher to ascertain lineal relationships and pleiotropic gene function in multicellular organisms. These mice may also be useful in studies of cell differentiation and mitosis.

| These Z/EG transgenic mice constitutively express lacZ under the control of the CMV enhancer/chicken actin promoter. Expression is widespread with notable exceptions being liver and lung tissue. Expression is observed throughout all embryonic and adult stages. When crossed with a Cre recombinase-expressing strain, lacZ expression is replaced with enhanced GFP expression in tissues expressing Cre. This double reporter system makes it possible to distinguish a lack of reporter expression from a lack of Cre recombinase expression while providing a means to assess Cre excision activity in live animals and cells.
As an example, when crossed to a strain expressing Cre recombinase in olfactory sensory neurons (see Stock No. 006668), this mutant mouse strain may be useful in lineage tracing. In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved t

| Mice homozygous for this bicistronic "yet40" allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. The IRES-EYFP is inserted downstream of the endogenous stop codon, allowing for normal expression of the endogenous gene and simultaneous EYFP reporter expression. ELISA assays confirm that p40 protein is expressed at similar levels in homozygous mutant and wildtype mice. The EYFP reporter marks dendritic cell (DC) and macrophage lineage cells that produce p40 following stimulation with toll-like receptor (TLR) ligands both in vivo and in vitro. These mice may be useful for labeling activated IL12/23 p40 expressing cells in studies of immunology and immunity, TLR signal cascades, cancer immunity, and vaccine development. | ||

| Mice that are homozygous for the CX3CR1-GFP targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. RT-PCR analysis of lymphoid tissue from homozygotes detects mutant gene product (mRNA) and no wild type gene product (mRNA). Flow cytometric analysis of peripheral blood cells identified a subset of green fluorescent cells not observed in wild type mice. Enhanced Green Fluorescent Protein (EGFP), but not the endogenous gene, is expressed in monocytes, dendritic cells, NK cells, and brain microglia, mimicking endogenous gene expression. The same subset of peripheral blood cells isolated from heterozygote mice express detectable levels of EGFP. Immunohistochemical analysis of spleen and peripheral nerve tissue from homozygotes does not detect EGFP.

| Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Homozygous mice have a chinchilla (gray) coat color, while heterozygotes have the typical black coat color expected for the C57BL/6J genetic background. Alpha (1,2) fucosylated glycans are not detected in the uterine epithelia from homozygotes at estrus. Beta galactosidase staining is detected in endocervial and uterine gland mucus secreting cells, stomach foveolar pit cells and chief cells, and colon goblet cells. The pattern of beta galactosidase activity mimics the endogenous expression pattern of the endogenous gene. This mutant mouse strain represents a model of the nonsecretor ABH histo-blood group antigen, which confers resistance to Norwalk virus infection, and may be useful in studies of reproductive biology, gastrointestinal tract epithelium, and the function of fucosylated glycans.

| Mice hemizygous for the smMHC/Cre/eGFP transgene (smMHCCre/eGFP) are viable and fertile, with the smooth muscle myosin heavy chain (smMHC or Myh11) promoter directing bicistronic Cre and EGFP protein expression to smooth muscle cells during development as well as in the adult mouse. Hemizygotes from founder line SMCG2 (SM2Cre/GFP) display intense EGFP fluorescence restricted to vascular and nonvascular smooth muscle, with strong concordance between cre expression and EGFP fluorescence (verifying the use of fluorescence as a marker for conditional gene recombination). When bred with mice containing a loxP-flanked sequence of interest, the resulting offspring can have Cre-mediated recombination of the flanked sequence in smooth muscle. Homozygotes are viable and fertile, with smaller litter sizes and a higher incidence of perinatal mortality.

| Mice hemizygous for the ChAT(BAC)-eGFP (ChATBAC-eGFP) transgene are viable and fertile, with the endogenous choline acetyltransferase (ChAT) transcriptional regulatory elements (cholinergic gene locus) directing enhanced green fluorescent protein (EGFP) protein expression during development as well as in the adult mouse. As such, EGFP is expressed in central and peripheral cholinergic neurons, including cell bodies and processes of the somatic motor, somatic sensory, and parasympathetic nervous system in gastrointestinal, respiratory, urogenital, cardiovascular, and other peripheral organ systems and neuromuscular junctions. These ChAT(BAC)-eGFP transgenic mice allow fluorescent visualization of cholinergic elements of the central and peripheral nervous system and may be useful for studying cholinergic neurotransmission and neuromuscular coupling. | ||

| These Thy1-Brainbow 2.1 (line R) transgenic mice are viable and fertile. The mice possess two invertible DNA segments (four fluorescent protein sequences in total) uniquely positioned in tandem and flanked with LoxP sites to generate a larger number of recombination outcomes; allowing stochastic expression of multiple fluorescent proteins from a single transgene. Although the fluorescent protein immediately adjacent to the promoter, hrGFPII (with nuclear localization signal), was designed to be expressed prior to Cre-mediated recombination, basal hrGFPII expression may not be observed in mouse tissues. When bred to Cre recombinase expressing mice, however, the resulting offspring can have one of three different inversions for each transgene in each cell of the cre expressing tissue(s).

| These ZW transgenic mice constitutively express lacZ under the control of the CMV enhancer/chicken actin promoter. Expression is widespread, but mosaic, throughout the central and peripheral nervous systems. Purkinje cells display intense beta-galactosidase activity. Approximately 50% of the total neuron population express the transgene, as detected by beta-galactosidase activity. Newborn mice exhibit widespread beta-galactosidase activity. When crossed with a Cre recombinase-expressing strain, lacZ expression is replaced with wheat germ agglutinin (plant lectin) expression in tissues expressing cre. The double reporter system makes it possible to distinguish a lack of reporter (lacZ) expression from a lack of Cre recombinase expression while providing a means to assess Cre excision activity at the individual cell level.

These transgenic mice express the membrane bound chicken ovalbumin OVA gene under the direction of the chicken beta actin promoter coupled with the cytomegalovirus (CMV) immediate-early enhancer. Chicken ovalbumin expression is detected by immunohistochemical analysis of all tissues. Splenocytes from transgenic mice display the 254-267-Kb complex, which is recognized by T-cells from the transgenic strain C57BL/6-Tg(TcraTcrb)1100Mjb/J (Stock No. 3831) and the 323-339-I-Ab complex, which is recognized by T-cells from the transgenic C57BL/6-Tg(TcraTcrb)425Cbn/J (Stock No. 4194).

| Homozygous Usp18 (or Ubp43) mutant mice on the FVB/N genetic background are viable and fertile, exhibiting none of the severe neurologic disorders that lead to embryonic lethality or early death reported for Ubp43-deficient mice on a C57BL/6 or mixed B6;129 genetic background. In contrast to wildtype mice, thymi from homozygous mice injected with LPS exhibit no protein from the targeted gene. Expression of the lacZ cassette is observed in both heterozygous and homozygous brain tissues. Homozygous mice are hypersensitive to type I interferon (IFN) and undergo apoptosis upon IFN stimulation. Ubp43-deficiency results in enhanced and prolonged STAT1 phosphorylation, DNA binding, and increased induction of hundreds of interferon stimulated genes (ISGs). Homozygous mice exhibit greater resistance to the cytopathic effects caused by a number of viruses (including lymphocytic choriomeningitis virus (LCMV), vesicular stomatitis virus (VSV), and Sindbis virus (SNV)).

In the initial characterization by the donating investigator, mice were either stillborn or survived 4-6 days. Mice that died at or shortly after birth were slightly smaller (1.33 g. vs. 1.51 g.) than normal littermates. Mice that survive for several days are indistinguishable from normal littermates in the first 48 hours, after which they exhibit decreased suckling and movement, labored breathing and tremoring limbs. Mice succumbing at this later time point are noticeably smaller than normal littermates (1.47 g vs. 4.59). A bell-shaped trunk is also noticeable in affected mice, presumably from intercostal muscle weakness, a characteristic of type I SMA.

| Mice that are homozygous for the targeted mutant Smn allele and homozygous for the SMN2transgene and hemizygous for the SMN1*A2G transgenes exhibit symptoms and neuropathology similar to patients afflicted with type III (mild) proximal spinal muscular atrophy (SMA). These same animals with only one copy of the SMN2transgene are 20%-40% smaller than unaffected mice. At 3 weeks of age they become less active and show signs of muscle weakness. The mice have a shortened lifespan (less than a year) near the end of which they exhibit reduced movement, diminished grooming, shallow breathing and considerable weight loss. Immunohistochemical analysis of spinal cord tissue from 1 month-old animals indicates the presence of cytoplasmic SMN protein and intranuclear aggregates (gems) of the SMN protein.

The Tg(SMN2*delta7)4299Ahmb allele consists of a SMA cDNA lacking exon 7 whereas the Tg(SMN2)89Ahmb allele consists of the entire human SMN2 gene. Mice that are homozygous for the targeted mutant Smn allele and homozygous for the two transgenic alleles exhibit symptoms and neuropathology similar to patients afflicted with proximal spinal muscular atrophy (SMA). At birth, triple mutants are noticeably smaller than normal littermates. By day 5, signs of muscle weakness are apparent and become progressively more pronounced over the following week as the mice display an abnormal gait, shakiness in the hind limbs and a tendency to fall over. Mean survival is approximately 13 days. Immunocytochemical analysis indicates that dystrophin expression is normal, however fibers isolated from the gastrocnemius muscle of a 14 day old triple mutant clearly show evidence of atrophy.

| Mice homozygous for this mT/mG mutation are viable and fertile. These mice possess loxP sites on either side of a membrane-targeted tdTomato (mT) cassette and express strong red fluorescence in all tissues and cell types examined. Tail or whole body epifluorescence is sufficient to identify mT/mG homozygotes. When bred to Cre recombinase expressing mice, the resulting offspring have the mT cassette deleted in the cre expressing tissue(s), allowing expression of the membrane-targeted EGFP (mG) cassette located just downstream. The donating investigator reports that the ACTB promoter allows stronger and persistent expression of the fluorescent proteins (especially in adult cells) compared to the endogenous Gt(ROSA) locus alone.

| Mice homozygous for the Notch reporter transgene are viable, fertile, normal in size, and do not display any behavioral abnormalities. Enhanced green fluorescent protein (EGFP) expression is present in a wide variety of hemizygous cell/tissue types during development and in the adult, including enriched hematopoietic stem cell (HSC) populations. The location of EGFP expression is consistent with Notch signaling pathway elements/genes and appears to faithfully reflect canonical (CBF1-mediated) Notch activity. With respect to hematopoiesis, low expression is shown in fully differentiated cells of the peripheral lymphoid organs (blood and spleen). Isolated HSC retain their ability to differentiate. Mice expressing this Notch reporter transgene may be useful in studying HSC populations and other cell types utilizing the Notch, CBF1, or Wnt signaling pathways.

| Mice heterozygous for this targeted mutation are viable and fertile. Homozygotes die from respiratory failure shortly after birth. Expression of the "knocked-in" lacZ gene is detected in a pattern similar to the endogenous transcript (in lung, skeleton, stomach, duodenum, spleen, and pancreas), and serves as a faithful reporter for Hedgehog (Hh) signaling. Because Hh and fibroblast growth factor (Fgf) signaling are abnormal, homozygous mice have defects in many Hh target tissues. Although the primary lung buds form in homozygotes, lung branching morphogenesis is defect beginning at 10.5 days postcoitus (dpc), and fails to generate a complete respiratory tree. The single left lobe also is significantly reduced, and total lung size at birth is diminished 67-75% compared to wildtype. In addition, homozygous mice have delayed mineralization of the endochondral skeleton, as well as impaired pancreas morphogenesis, islet formation and endocrine cell proliferation.

| Mice homozygous for the targeted mutation fail to develop a pancreas. Heterozygous mice have normal pancreas development but partially impaired glucose tolerance in adulthood. The substitution of the targeted gene with tTAoff inactivates the endogenous allele and places tTAoff expression under the control of the endogenous transcriptional regulatory sequences. tTA expression from the modified locus is identical to that of the normal allele; tTA mRNA is detectable in the pancreas but not in other visceral organs or salivary glands. This mutant may be useful in studies of pancreatic endocrine/exocrine function and diabetes. Heterozygotes also can be bred with transgenic mice that express a target gene under the regulation of a tetracycline-responsive element (TRE; tetO) for pancreas-specific applications.

Expression of the bicistronic transgene is under the regulation of a tetracycline promoter element (TRE; tetO). By themselves, these transgenic mice do not express EGFP, but when these mice are mated with a second transgenic strain expressing tetracycline-transactivator (tTA) protein under the control of a tissue-specific promoter, Ipf1 and EGFP are highly expressed in the appropriate tissue of bitransgenic offspring.
This mouse was originally designed to be mated to an apancreatic targeted mutant with tTAoff in place of the endogenous Ipf1 gene (see Stock No. 005701). The combined mutations allow normal pancreatic dev

| Hemizygous transgenic mice are viable, fertile, normal in size, and do not display any behavioral abnormalities. Expression of the bicistronic transgene is under the regulation of a tetracycline-responsive promoter element (TRE; tetO). When transgenic mice are bred to a second transgenic strain expressing tetracycline-transactivator (tTA) protein under the control of a tissue-specific promoter, the bitransgenic offspring express Ipf1 and lacZ in the appropriate target tissue. Further, Ipf1 and lacZ expression in bitransgenic mice can be suppressed by administration of the tetracycline analog, doxycycline. All cells expressing Ipf1 coexpress the reporter, and mRNA levels of the transgenic and endogenous Ipf1 fluctuate in concert during development. This mouse was designed originally to be mated to an pancreatic targeted mutant with tTAoff in place of the Ipf1 gene (see Stock No. For more information please see the full descriiption on the strain data sheet | ||

New Strains Under DevelopmentThe Jackson Laboratory serves as a worldwide distributor and national repository for common and rare strains of inbred mice and mice carrying spontaneous mutations or induced mutations (i.e., transgenic, targeted/"knockout", or chemically induced mutations). At any one time, we have over 100 strains at various stages of development and colony expansion. Strains "Under Development" fall into two categories depending on the anticipated demand from the scientific community.
- Receive periodic updates on the status of the colony UNDER DEVELOPMENT
- Obtain advance notification of strain availability and opportunity to order prior to the strain being published as available
- Provide input affecting speed and quantity of availability
It is VERY IMPORTANT that you register interest in strains Under Development. The anticipated demand for a strain enables us to determine effectively the distribution plan for each strain Under Development. Registering interest also provides benefits to you (including advance notification of pending availability). Whether a strain is made available from a live colony OR from our cryopreservation repository, you may want to consider the option of Dedicated Supply. To learn more about Dedicated Supply, go to Services.
- Strains that will be made available from a live distribution colony at The Jackson Laboratory.
These strains are designated as: "Under Development for Distribution Colony"- Strains that will be made available through the Cryopreservation Repository.
