Allelic Composition Genetic Background
Bltp2em1(IMPC)J/Bltp2em1(IMPC)J embryos alive at E10.5 exhibit heart defects and some have abnormal head shape and blood pooling. All mutants recovered at E11.5 are smaller and most are abnormal although a few appear normal.Bltp2em1(IMPC)J/Bltp2em1(IMPC)JC57BL/6NJ-Bltp2em1(IMPC)J/Mmjax
Placental phenotype in Bltp2em1(IMPC)J/Bltp2em1(IMPC)J (Bltp2 -/-) mice. E10.5 placentas show a diminished spongiotrophoblast layer, moderate labyrinth zone defects, and impaired chorioallantoic branching.Bltp2em1(IMPC)J/Bltp2em1(IMPC)JC57BL/6NJ-Bltp2em1(IMPC)J/Mmjax
E9.5 Bltp2em1(IMPC)J/Bltp2em1(IMPC)J (-/-) embryos are generally smaller but display appropriate germ layer development.Bltp2em1(IMPC)J/Bltp2em1(IMPC)JC57BL/6NJ-Bltp2em1(IMPC)J/Mmjax
E10.5 Bltp2em1(IMPC)J/Bltp2em1(IMPC)J are smaller and exhibit blood pooling.Bltp2em1(IMPC)J/Bltp2em1(IMPC)JC57BL/6NJ-Bltp2em1(IMPC)J/Mmjax
