• width of corpus callosum in newborn mice
• all major brainstem motor nuclei present in newborn (P0) mice including facial, trigeminal and hypoglossal, and ambiguus nuclei and dorsal motor nucleus of vagus nerve
• retrotrapezoid nucleus/parafacial respiratory group and pre-Boetzinger complex primary respiratory phase oscillators present in newborn (P0) mice and of normal morphology
• delayed colonization of intestines by enteric neural crest-derived cells (ENCCs), as determined by Sox10 staining in E12.5 embryos
• in newborn mice

• mice born with significantly lower body weight

mortality/aging
• pups die within 3-4 hours after birth

skeleton
N
