Embryonic defects in Ptentm1Mak/Pten+

mortality/aging

growth/size/body
• the majority of embryos are smaller but have normal body symmetry and development of most organ systems

embryo
• majority of embryos remain unturned
• the majority of embryos are smaller but have normal body symmetry and development of most organ systems
• severely affected (about 5%) embryos have little or no development of the major organ systems, including the heart and brachial arches
• severely affected (about 5%) embryos have asymmetrical head folds
• neural tube is open along the entire length of the embryo
• neural tube is kinked along the entire length of the embyo
• the remaining 20% of moribound embryos display other placental abnormalities including disorganization of the spongiotrophoblast layer and limited invasion of the trophoblast layer by the chorion
• the allantois fails to fuse to the chorion at E9 in 80% of dying embryos
