Umbilical hernia in Gad1tm1.1Bgc/Gad1tm1.1Bgc mice

craniofacial
cleft secondary palate ( J:158888 )
• at P0
• injection of pregnant dams with muscimol (a GABA agonist) partially rescues the cleft palate phenotype
failure of palatal shelf elevation ( J:158888 )
• at E14.5
• however, in culture palatal explants are able to undergo elevation and fusion

embryo
umbilical hernia ( J:158888 )
• umbilical hernia is seen in most (85%) pups at P0

digestive/alimentary system
cleft secondary palate ( J:158888 )
• at P0
• injection of pregnant dams with muscimol (a GABA agonist) partially rescues the cleft palate phenotype
failure of palatal shelf elevation ( J:158888 )
• at E14.5
• however, in culture palatal explants are able to undergo elevation and fusion

growth/size/body
cleft secondary palate ( J:158888 )
