Allelic Composition Genetic Background
Stt3bem1(IMPC)J/Stt3bem1(IMPC)J (-/-) embryos at E9.5 are often small and occasionally show cardiac or pericardial edema. E10.5 mutants are developmentally delayed, show abnormal heart and yolk sac morphology, and abnormal heart shape and branchial arches.Stt3bem1(IMPC)J/Stt3bem1(IMPC)JC57BL/6NJ-Stt3bem1(IMPC)J/Mmjax
At E9.5, Stt3bem1(IMPC)J/Stt3bem1(IMPC)J (-/-) embryos display normal germ layers.Stt3bem1(IMPC)J/Stt3bem1(IMPC)JC57BL/6NJ-Stt3bem1(IMPC)J/Mmjax
