ES Cell to Mouse Model Service
How can a genetically modified mouse help your research?
The ability to genetically modify mice is a powerful tool used in basic and applied research with many applications to the study of gene function and human disease. A global initiative is systematically attempting to disrupt the function of every mouse gene by generating conditional gene-target and/or gene trap embryonic stem (ES) cell lines for all 20,000+ genes in the mouse genome. This will enable scientists to make low-cost mouse models related to their gene of interest. Once phenotyped, these mouse models will provide invaluable insights into human gene function with wide-ranging clinical implications, including better understanding of diseases and discovering gene targets for therapeutic agents.
What does the service do?
The Australian Phenomics Network (APN), through Monash University, provides a centralized service for the generation and distribution of heterozygous mice from frozen, genetically modified ES cell lines imported from the International Gene Trap Consortium (IGTC), the Knock Out Mouse Project (KOMP) and other repositories around the world. Through the APN, Australian researchers can simply interrogate the international ES cell databases, choose the genetically modified ES cell line(s) of interest, lodge a request with the APN, and within months can have mice that are heterozygous for the modified gene delivered to their laboratory at an affordable cost.
Australian researchers are able to access this service by contacting the APN ES Cell to Mouse Service Manager at Monash University at apn.esmouse@med.monash.edu.au. (Full contact details are found under the 'ES Cells to Mouse' tab above). You may be interested to see what ES cell lines are available or in the pipeline by accessing the international databases listed in “What are the sources of ES cells? — Click the 'ES Cells to Mouse' tab above, then click the link 'What are the sources of ES cells?'.
What is the basis of the technology?
Gene-target and gene trap vectors used in creating the ES cells that are used by the ES Cell to Mouse Service are designed to insert into the mouse genome and disrupt gene function. They usually result in a null allele, producing either no protein or a truncated/internally-deleted protein.
Why use the APN ES Cell to Mouse Service?
The advantages of using this system include the following:
- A time-efficient, quality-assured and affordable way to obtain a genetically modified mouse model for your gene of interest.
- A cost-effective alternative to traditional knock-out strategies.
- A complimentary model to compare with traditional full gene “knock-outs” and ENU-induced mutant mice carrying point mutations.
For further details of this service, please see the 'ES Cell to Mouse' tab above.
ENU Models
ENU mutagenesis provides a phenotype driven approach for obtaining mouse models of human conditions. The APN can provide the expertise, scale and resources upon which researchers can significantly expand the scope of their research endeavours.
The Technology
The basis of the ENU mutagenesis approach lies in the chemical mutagen ENU (ethyl-nitrosourea), which incorporates point mutations on a genome wide scale in premeiotic spermatogonial cells. This allows for the production of a number of genetically unique offspring from a single ENU-mutagenised male.
ENU Mutagenesis can be carried out on an inbred strain or on a sensitised background, such as an established transgenic/knockout line.
These libraries of ENU mutagenised mice are then subjected to a robust phenotypic screen. The unique approach provided by the APN enables researchers to custom-design their phenotypic screen, allowing for the isolation of phenovariants that show abnormalities directly related to the researcher’s specific pathway of interest.
Once heritability of the phenotype is confirmed, the chromosomal location of the causative mutation is identified via SNP-based genome scans against a mapping strain. Exonic sequencing then rapidly identifies the SNP of interest.
Advantages
One benefit of the ENU mutagenesis approach is the unbiased identification of novel alleles. Upon initiating the screening process, no assumptions are made as to the physiological role of a gene or its products.
Other advantages offered by this approach are numerous, including:
- Revealing domain specific effects of the gene product,
- Providing a more accurate representation of human conditions through point mutations rather than entire gene knockouts,
- Development of pre-clinical animal models of human disease,
- Revealing previously unknown genetic components and mechanisms,
- Allowing the researcher to focus on their disease or pathway of interest.
Recessive or Dominant
This approach can be applied for discovering mutations that are inherited in both a dominant and recessive manner.
The phenotypic effect of an allele inherited in a recessive manner can only be visualised when the allele has been brought to homozygosity. Details of the recessive ENU model can be found on the — 'Recessive ENU' tab above.
The phenotypic effect of an allele inherited in a dominant manner can be visualised in the heterozygote state at G1. Details of the dominant ENU model can be found on the — 'Dominant ENU' tab above.
ES Cell to Mouse Service
The Embryonic Stem (ES) Cell to Mouse service provides ready access to the global initiative to systematically inactivate every mouse gene and generate conditional gene-target and/or gene-trap mouse models for all 20,000+ genes in the mouse genome. This service enables Australian researchers to interrogate the international ES cell databases and choose the genetically modified ES cell line(s) of interest. You can then lodge a request, and within months have heterozygous mice delivered to your laboratory, ready to advance your research.

How are ES cells made into a mouse?
Mouse ES cells are electroporated with the gene-target or gene-trap vectors and the resultant genetically modified ES cell line is then stored in an ES cell library. Once these ES cell lines have been established, they can be microinjected into mouse blastocysts and implanted into pseudopregnant female mice. The pups generated are assessed for the degree of chimerism and high percentage chimeric animals are crossed with wild type mice to obtain germline transmission of the mutant allele. The resulting heterozygotes are shipped to the researcher for breeding to homozygosity and characterisation.
What does the service offer?
The service offers centralised access to international repositories of genetically modified ES cells, including the following components:
- Advice regarding the ES cell lines available.
- Ordering and importation of your selected ES cell line from the international repository.
- Expansion of the ES cell line.
- Confirmation of vector integration (if not provided by the supplier) and karyotyping of gene trapped clones, thereby providing verification of the genotype from ES cell genomic DNA.
- Microinjection of the selected ES cell line into blastocysts to generate chimeric mice.
- Breeding of chimeric mice to obtain germline transmission of the targeted or trapped mutation.
- Generation and delivery of a heterozygous breeding pair of the new mouse strain to your animal facility or laboratory.
- Supply of the originating ES cell line, if required for in vitro experiments. (Please note, these cells will be heterozygous for the mutant allele.)
- Provision of a protocol for a PCR-based genotyping assay to assist with maintaining your mouse colony or ES cell line. Please note, this protocol will test for the presence of the ?-geo cassette only and is suitable for determining animals that are heterozygous for the mutant allele. A number of genotyping protocols are available on the Sanger Institute Gene Trap Resource (SIGTR) web page click on the ‘Protocols’ link found in the navigation bar on the left hand side of the Sanger Institute page.
How do I access the service?
There are three separate databases in which you should search for the availability of an ES cell line containing a variant of your gene of interest. Searching each of these databases is described below in this section. Note the ID number and other details of any potentially useful ES cells lines that you find and include them in your email enquiry to the APN Monash Node Manager. Even if you are unable to find what you are looking for still contact the node manager, who may be able to help.
Searching for gene trap embryonic stem cell clones on the International Gene Trap Consortium (IGTC) database
- Go to www.genetrap.org/index.html.
- Click on the ‘DATA ACCESS’ tab at the top of the page.
- Select ‘Keyword/ID search’ from the drop down menu. The default settings are generally suitable for most searches.
- Under ‘Search Terms’ type the name of the gene of interest or the gene symbol and click on ‘Search’. If the gene you have entered is represented in the database the next page will show a record of the Gene Description, the Symbol and the Chromosome on which it is located.
- Click on the entry under ‘Gene Description’ to see what gene trapped cell lines are available. The next page contains detailed information about the gene and a listing of cell lines.
- Under the heading ‘Cell Lines’ click on the arrow to display all of the lines.
- Click on the ‘Cell Line ID’ you will find details of the particular gene trapped cell line including a sequence tag, which will give you information about the position of the gene trap in the gene.
Searching for gene targeted embryonic stem cell clones on the Knockout Mouse Project (KOMP) and European Conditional Mouse Mutagenesis program (EUCOMM) databases.
To search the KOMP database:
- Go to www.komp.org/
- Enter the gene name or symbol in the ‘Search gene or ID’ box and click ‘Enter’.
On the results page click on the entry that best matches the gene you are looking for (if there is more than one entry). - Under the heading ‘Targeting Projects’ you will find a project ID and a diagram indicating the projects current status in the pipeline.
- Click on the ‘Project ID’ number to open a new window where you will find further details of the project. You may also find the message ‘Unfortunately we have no KOMP products available…’ after your initial search. If this is the case there may still be something listed under the heading ‘Targeting Projects’ which has been generated by another group. You will also see at the top right of this page the heading ‘Additional Resources’ where you will often find ‘IGTC’ (International Gene Trap Consortium) or ‘IMSR’ (International Mouse Strain Resource) listed, clicking on these links will take you to listings of gene traps or other targeted clones in these databases.
To search the EUCOMM database
- Go to www.eucomm.org/.
- Enter the gene name or symbol in the search box; the search will begin automatically once you have stopped typing. The search results will show the group working on this gene denoted by a single letter code, moving the cursor over these letters will show you the group name. The results table also shows the status of the project as well as other information.
- At the end of each entry is a ‘view’ link that will take you to a page containing specific information about the targeting strategy and the targeting vector.
How long will it take?
From the time the order is placed it could take from 6 - 8 months to have the requested mice ready to ship from Monash University to your mouse facility. This time includes establishing a Material Transfer Agreement with the ES cell repository, receipt of the ES cells, verification of the cell line, and generation of the mice.
Will I need to rederive the mouse strain into my institutional animal facility?
The need to rederive will depend on the policy of your mouse facility. You will need to check with your animal unit manager, who will assess the health status of your new mouse strain.
Do I need animal experimentation ethics approval?
The APN has current animal ethics approval and International Bioethics Committee approval for the work required to produce heterozygous mice at Monash University. Before mice can be shipped to the researcher’s mouse facility, it is the responsibility of each recipient to apply, through their own local ethics committee, for approval to house and handle the mice.
What is a gene-trap allele?
Gene-trap vectors are designed to insert into the mouse genome and disrupt gene function; usually resulting in the production of a truncated fusion protein from the gene in which it has inserted. Click here for the Gene Trap Factsheet.
What is a targeted allele?
Gene-targeting vectors are designed to target a specific region of the gene of interest resulting in inactivation of the gene. In many cases the vectors create a conditional knockout that allows for tissue specific inactivation of the gene. Click here for the Gene-targeting Factsheet.
What are the sources of ES cells?
- International Gene Trap Consortium www.genetrap.org
- Knock Out Mouse Project www.komp.org
- European Conditional Mouse Mutagenesis Program www.eucomm.org

Recessive ENU Models
The Recessive ENU service provides researchers with ENU gene variant mouse strains that are characterised by recessive inheritance for their phenotypic trait.
ENU mutagenesis is a phenotype driven approach for obtaining mouse models of human conditions. The strength of the ENU mutagenesis approach lies in the chemical mutagen ENU (ethylnitrosourea), which incorporates point mutations on a genome wide scale in premeiotic spermatogonial cells. This allows for the ongoing production of a number of genetically unique offspring from a single ENU-mutagenised male used to create a library of novel gene function variants.
Most of the variant mice will contain point mutations, meaning that they are more reflective of the mutations that naturally occur in the human genome. ENU Mutagenesis can be conducted on an inbred strain or on a sensitized background, such as an established transgenic/knockout line.
These libraries of ENU mutagenised mice are then phenotypically screened for phenotype. This approach enables researchers to custom-design their phenotypic screen, allowing for the isolation of pheno-variants that display characteristics directly related to the researcher’s specific pathway of interest. Pedigrees that do not produce a phenotype of interest in G3 are abandoned, while those that do are carried forward to establish heritability.
This service is accessible through the Australian Phenomics Facility (APF), Canberra, and the Centenary Institute of Cancer Medicine and Cell Biology (The Centenary Institute), Sydney.
The Recessive ENU service provides researcher with access to other NCRIS funded ENU-recessive variants and identified genetic variants of relevance to various areas of study. Through the Centenary Institute, researchers have access to mouse models of relevance to the study of infection and immunity, and the APF covers a broad range of variants. The APN service supplements researchers by providing access to phenotyping equipment, project design and project management services.
Funding from the federal government through the National Collaborative
Research Infrastructure Strategy (NCRIS) will allow researchers to access the APN Recessive ENU derived mice and the related services at a reduced cost.

ENU Recessive Screens
As depicted in Figure 1, the first generation (G1) of mice produced from an ENU mutagenised male only carry one copy of any given mutation. While a screen for dominant-acting mutations can be carried out at this stage, a recessive mutation would not exhibit its phenotypic characteristics at G1.
Each recessive pedigree begins with the pairing of two unrelated G1s for the production of G2 offspring, 50% of which are heterozygous for the causative mutation.
By intercrossing G2 siblings, the mutation is brought to homozygosity in 25% of G3 siblings. It is at this stage that the first screen takes place.
Pedigrees that do not produce a phenotype of interest in G3 are abandoned, while those that do are carried forward to establish heritability.
Heritability is confirmed by the emergence of the phenotype of interest in subsequent generations. Once heritability is established, the strain is fixed through several generations of breeding, thus providing an ongoing supply of phenovariants for further characterisation.
Mapping of the causative mutation forms the next stage of the process. Consecutive stages of breeding to a mapping strain introduce recombination events, narrowing the region in which the mutation is located. Discovery of the mutation location forms the final stage of the mapping process.
Figure 1: The strategy for production of ENU mutagenised pedigrees for a recessive screen
Dominant ENU Models
The Dominant ENU service provides researchers with access to ENU gene variant mouse strains that are characterised by dominant inheritance for their phenotypic trait.
ENU mutagenesis is a phenotype driven approach for obtaining mouse models of human conditions. The basis of the ENU mutagenesis approach lies in the chemical mutagen ENU (ethylnitrosourea), which incorporates point mutations on a genome wide scale in premeiotic spermatogonial cells. This allows for the production of a number of genetically unique offspring from a single ENU-mutagenised male to create a variant library.
ENU Mutagenesis can be conducted on an inbred strain or on sensitised background, such as an established transgenic/knockout line.
As ENU-derived dominant variants are identified at the first generation, researchers are able to undertake proof-of-principle evaluations on the variant strains in short timeframes. Many of the variant mice will contain point mutations, meaning that they are more reflective of the mutations that occur in the human genome.
The APN Dominant ENU service is accessible through The Walter and Eliza Hall Institute, Melbourne, the Queensland Institute of Medical Research, Brisbane, and The Menzies Research Institute, Hobart. Staff at these institutions have extensive training and experience in the care and production of mouse strains.
The Dominant ENU nodes provide access to mice heterozygous for random ENU-induced mutations. Access is open to any not-for-profit researcher who can integrate into the current research program without compromising output for other customers. Priority is allocated on a first come, first served basis. As with all APN activities, promotion for the Dominant ENU service will be coordinated by the APN project officer based at ANU in Canberra, and via the APN website and newsletters. In addition, when mice with defined characteristics are identified, the WEHI node manager (Benjamin Kile) will approach Australian researchers with skills in the relevant in the area.
Funding from federal government through the National Collaborative Research Infrastructure Strategy (NCRIS) and State funding from the Victorian Government allows researchers and other collaborators to access Dominant ENU generated mice at a reduced cost.

Histopathology and Organ Pathology
Overview
The Histopathology and Organ Pathology service helps researchers across Australia in histological preparation and in analysing histological images and data on specific mice or mice at certain developmental stages. It also generates histological and organ pathology data on mouse models created through the APN.
This service has Digital Slide Scanners (see Zeiss Mirax Digital Slide Scanner details below) capable of producing high quality digitally accessed images of stained slides. Data files are downloadable by e-research fibre-optic links through the IMVS. It also offers the latest Histology capabilities, including confocal microscopes, multi-colour fluorescence microscopy and high resolution white-light microscopy all with electronic image capture.
Staff providing this service have extensive histology, diagnostic and electronic imaging experience. A comparative Pathologist is available at the IMVS site and the Melbourne site has secured the services of consultant Medical and Veterinary Pathologists to provide expert advice.
The APN Histopathology and Organ Pathology service is based at the Department of Anatomy and Cell Biology at The University of Melbourne and through the Veterinary Service Division at the Institute of Medical and Veterinary Science (IMVS) in Adelaide. Samples can be sent to either location.
Zeiss Mirax Digital Slide Scanner
The Zeiss Mirax Digital Slide Scanner is a high resolution, high through-put scanning device capable of imaging standard stained histological slides and slides with specialist staining. Digital images are saved to the server and can be interrogated by the client using the free Mirax Teleconsulting software www.zeiss.com/mirax as required. This service is due to commence in May 2008 and updates on the service will be posted on the Department of Anatomy and Cell Biology web page www.anatomy.unimelb.edu.au under Digital Slide Scanner Services.

Clinical Pathology
The Australian Phenomics Network can now provide a service of haematological analysis of mouse blood samples.
An Advia 2120 haematology analyser is available at the Australian Phenomics Facility in Canberra.
This machine is capable of analysing;
- Complete Blood Counts
- Differentials
- Reticulocytes
The machine has the capability of running mouse samples using its multispecies software package and currently has reference ranges for C57Bl/6 mice and Balb mice.
- The machine requires a minimal sample volume of 175uL to perform a screen. We are also currently developing a dilution system, whereby smaller volumes of blood may be able to be used.
- We ask for a minimum of 200uL to be shipped to the facility at this stage.
The Australian Phenomics Facility is available to run samples for Australian researchers on a cost recovery basis.
- Blood samples can be shipped to the facility for analysis. Samples should preferably arrive Tuesday to Thursday to ensure prompt sampling. A minimum of 48 hours notice is required prior to shipment.
Sampling
Blood is to be collected in EDTA. The method of collection is at the discretion of the researcher, however, it is important to note that the sample should be collected into EDTA as soon as possible to minimise clot formation. Ethics approval may be required from your facility for samples taken from live mice.
- Samples must be of excellent quality with no clots as this will give erroneous results and potentially inhibit the ability to run the sample.
Shipping
- Samples should be shipped on frozen gel packs in an esky to maintain a cool temperature (below 4°C).

Strain Repository
The Strain Repository service comprises of two components:
Both services are provided through the Australian Phenome Bank (APB).
Strain Archiving Service
The APB archives mouse strains as cryopreserved sperm or embryos. The aim of this service is 3-fold:
- it acts as an insurance against disaster;
- archiving removes the cost and effort of maintaining strains “on the shelf” just in case they are needed in the future and;
- archiving preserves strains for future use.
The depositing researcher maintains ownership of the strain and can nominate/confirm availability to other researchers.
Financial support for sperm/embryo cryopreservation* is available if the strain:
- has not been frozen in the APB previously;
- has a heritable phenotype, and;
- it will be made available to other researchers, immediately if already in public
domain (published) or after a maximum period of 2 years if not currently in
the public domain.
*Support is available for embryo freezing if the strain cannot be frozen down as sperm.
Sperm cryopreservation and archiving is conducted at Monash University (Melbourne) and the ANU (Canberra). Embryo cryopreservation and archiving is conducted at ARC (Perth). A re-animation service is available on a cost recovery basis.
Mouse Strain Database
The APB maintains, with researcher input, a database held around Australia of live and frozen stock. The database allows researchers to search and determine availability of strains of interest to their work. This contributes to saving research dollars by avoiding multiple importations or duplication of effort to produce strains that are already available in the country as either live or frozen stock.
As strains are created or imported by researchers, they are able to register the strain within the APB. The listing researcher maintains ownership of the strain and can nominate the availability to other researchers, including passing on existing terms and conditions of access.
The database lists fields such as phenotype, genotype, affected gene (if known), allele (if known), method of production (e.g. Tg/KO/ENU) and status (frozen or alive). The database also links to other databases such as Mouse Genome Informatics (MGI) and PubMed.
