Image Caption Genotypes involving this allele
Allelic Composition Genetic Background
Rprd2em1(IMPC)J/Rprd2em1(IMPC)J embryos are developmentally delayed, show impaired embryo turning, abnormal head shape, caudal neural tube kinks and incomplete cranial neural tube closure, abnormal heart morphology and abnormal yolk sacs.Rprd2em1(IMPC)J/Rprd2em1(IMPC)JC57BL/6NJ-Rprd2em1(IMPC)J/Mmjax
Placental abnormalities in Rprd2em1(IMPC)J/Rprd2em1(IMPC)J (-/-) embryos include diminished spongiotrophoblast layer, abnormal chorioallantoic interface, impaired chorioallantoic branching, and multiple labyrinth zone defects.Rprd2em1(IMPC)J/Rprd2em1(IMPC)JC57BL/6NJ-Rprd2em1(IMPC)J/Mmjax
E8.5 Rprd2em1(IMPC)J/Rprd2em1(IMPC)J embryos are slightly delayed but display typical germ layer patterning.Rprd2em1(IMPC)J/Rprd2em1(IMPC)JC57BL/6NJ-Rprd2em1(IMPC)J/Mmjax
E9.5 Rprd2em1(IMPC)J/Rprd2em1(IMPC)J embryos are delayed yet they maintain appropriate expression of key markers in all 3 germ lineages.Rprd2em1(IMPC)J/Rprd2em1(IMPC)JC57BL/6NJ-Rprd2em1(IMPC)J/Mmjax
