Donating InvestigatorDr. Caroline Damsky,   Univ of California, San Francisco

Description
Mice homozygous for the Itgb1tmlLscd targeted mutation die during early postimplantation development. Beta1-null embryos form normal-looking blastocysts and initiate implantation at E4.5. By E5.5, Beta1-null embryos degenerate extensively. The inner cell mass region of blastocyst outgrowths show highly retarded growth and defective extra-embryonic endoderm morphogenesis and migration.

Control Information

  Control
   See control note: Wildtype mice from the colony may be used as controls. This strain is a mixture of C57BL/6 and 129 inbred strains and the Swiss Webster Black random bred strain.

        involves: 129X1/SvJ * Black Swiss
  • mortality/aging
  • complete embryonic lethality between implantation and somite formation
    • lethality occurs between E4.5 and E5.5 due to inner cell mass defects   (MGI Ref ID J:28266)
  • embryogenesis phenotype
  • abnormal blastocoele morphology
    • E4.5 embryos have collapsed blastocoeles   (MGI Ref ID J:28266)
  • abnormal inner cell mass morphology
    • isolated inner cell masses attach, spread and differentiate very poorly on a fibronectin substrate   (MGI Ref ID J:28266)
    • inner cell mass degeneration
      • inner cell mass of cultured blastocytes have highly restricted growth and defective endoderm morphogenesis and migration   (MGI Ref ID J:28266)
      • 48 hours of blastocyst culture in serum leads to inner cell masses that are significantly smaller and appear disorganized compared to controls   (MGI Ref ID J:28266)
  • abnormal trophoblast layer morphology
    • the trophoblasts of E4.5 embryos fails to extensively invade the maternal decidua   (MGI Ref ID J:28266)
    • trophoblast outgrowth from cultured blastocytes is defective when laminin is provided as a substrate   (MGI Ref ID J:28266)
  • abnormal visceral endoderm morphology
    • the monolayer of visceral endoderm is not formed in these inner cell masses despite the presence of laminin-positive cell clusters   (MGI Ref ID J:28266)
    • only 3 of 17 inner masses demonstrate any morphogenesis of the endoderm under this conditions compared to the 100% morphogenesis that occurs to controls   (MGI Ref ID J:28266)

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.
