Knockout Mouse Phenotyping Program Highlights
Investigators at The Jackson Laboratory have developed a novel approach that enables highly efficient generation of mouse strains from Embryonic Stem Cells (ESC). This advance overcomes a major limitation in mutant mouse production; namely, the uncertainty of whether the desired mutation created in ESC is incorporated into the mouse’s reproductive cells so that it is passed along to offspring. This process has been slow, laborious, and expensive. The Perfect Host technology ensures that ESC chimeras have gametes derived only from the ESC cell carrying the desired mutation. Thus all offspring are paternally derived from the ESC and will carry the mutation. This research was made possible through support from The Jackson Laboratory, the Maine Technology Institute, in addition to several NIH Institutes and Centers, including KOMP and the use of KOMP-generated ESC cell lines. This new technology will be extremely useful for the KOMP2 program, by reducing the number of mice needed for each experiment, and greatly increasing the speed and efficiency of mouse production.
Read an interview with KOMP2 awardee Dr. Monica Justice from Baylor College of Medicine, in which she discusses her career path, current work in hematopoietic cancers and genetic syndromes, and future goals for the KOMP2 project. Find out how her early years on the farm inspired a love of biology, what experiences sparked her interest in pediatric medicine, and how she enjoys spending time outside of the lab.
Funding Opportunity Announcement to phenotype embryonic lethal knockout mice from the International Mouse Phenotyping Consortium (IMPC)!
The IMPC, a worldwide consortium that includes KOMP2 as a member, is generating an estimated 20,000 knockout mouse strains, up to 30% of which are expected to be embryonic or perinatal lethal. This funding opportunity announcement invites applications to phenotype embryonic lethal mouse strains with a long term goal of revealing important insights into normal development in addition to a variety of diseases. This funding opportunity is supported by several NIH Institutes and Centers, and is related to, but separate from, the Common Fund’s KOMP2 program.

Seven new projects receive NIH Common Fund support in fiscal year 2011 via the KOMP2 program. The program is creating a valuable genetic resource for revealing mammalian gene function, providing insight into genes that affect human health and disease.
