N normal phenotype
mortality/aging
• mice die between E10.5 and E11.5 due to defects in the placental labyrinth architecture

embryo
N
• despite defects in placenta labyrinth vasculature, mice exhibit normal embryonic and yolk sac vasculature
• mice exhibit patchy and discontinuous collagen IV and laminin staining of the placenta labyrinth basement membrane
• the basement membrane of the placenta labyrinth is disorganized
• mice exhibit defects in placental labyrinth vascularization consisting of a lack of fetal blood vessels and reduced trophoblast layer
• the trophoblast layer is compact due to decreased branching morphogenesis comapred to in wild-type mice
