Caption: E9.5 Arpc1aem1(IMPC)J/Arpc1aem1(IMPC)J embryos have abnormal head shape, sometimes with incomplete cranial neural tube closure, and about half have branchial arch/pouch abnormalities and abnormal cardiac development. E10.5 embryos are dysmorphic or dying. (details)

Caption: Arpc1aem1(IMPC)J/Arpc1aem1(IMPC)J (-/-) placentas have an expanded spongiotrophoblast layer, multiple labyrinth zone defects, and nearly absent chorioallantoic branching at E10.5. (details)

Caption: Despite gross abnormalities including an open cranial neural tube and severely dysmorphic head and pericardial edema, all Arpc1aem1(IMPC)J/Arpc1aem1(IMPC)J embryos display appropriate germ layer patterning at E10.5. (details)
