mortality/aging
• pups die within one day of birth
|
• some embryos die before E14.5
|
immune system
• in lethally irradiated wild-type mice receiving mutant fetal liver cells, IgGA levels are significantly lower than controls
|
• in lethally irradiated wild-type mice receiving mutant fetal liver cells, IgG2a levels are significantly lower than controls
|
• in lethally irradiated wild-type mice receiving mutant fetal liver cells, IgG2b levels are significantly lower than controls
|
nervous system
• glial fibrillary acidic protein(GFAP)-positive astrocytes are not present in the marginal zone of cervical spinal cord of E18.5 embryos
• GFAP-positive acstrocytes do no develop from neural explants of E14.5 cerebral cortices in the presence of IL-6, ciliary neurotrophic factor, or oncostatin M
|
hematopoietic system
• there is a two-thirds reduction in CFU-M isolated from the bone marrow when macrophage-colony stimulating factor is used as a stimulus
|
• in lethally irradiated wild-type mice receiving mutant fetal liver cells, IgGA levels are significantly lower than controls
|
• in lethally irradiated wild-type mice receiving mutant fetal liver cells, IgG2a levels are significantly lower than controls
|
• in lethally irradiated wild-type mice receiving mutant fetal liver cells, IgG2b levels are significantly lower than controls
