Donating InvestigatorDr. Jurrien Dean,   NIH

Description
Mice that are homozygous null for the Zp2 gene are viable, normal in size and do not display any gross physical abnormalities. No Zp2 gene protein product is immunodetectable in ovary tissue. Although the ovaries appear normal with follicles at all stages of development present, homozygous females are infertile. A thin zona matrix is present in early follicles but is not sustained in pre-ovulatory follicles. The abnormal zona matrix does not affect initial folliculogenesis, but there is a significant decrease in the number of antral stage follicles in ovaries isolated from mice lacking a zona pellucida. Few eggs are detected in the oviduct after stimulation with gonadotropins, and no two-cell embryos are recovered after mating Zp2-null females with normal male mice. Although zona-free oocytes mature and can be fertilized in vitro and successfully progress to the blastocyst stage, the developmental potential of blastocysts derived from homozygous Zp2-null eggs appears compromised. The donating investigator has not observed live births when fertilized null eggs are transferred to foster mothers. Male homozygotes are fertile and phenotypically normal.

Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt a 5' region of the Zp2 gene (exons 1-2). The construct was electroporated into 129X1/SvJ x 129S1/Sv-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6N blastocysts. The resulting chimeric animals were crossed to outbred CF1 mice.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
