mortality/aging
• lethality between E11 and E13
|
growth/size/body
• slightly smaller size from E10.5 on
|
embryo
• the network of embryonic vessels and maternal sinuses in the placenta are poorly developed
• by E12.5, dilation of maternal and embryonic vessels and pooling of maternal blood in the labyrinthine layer of the placenta are observed
|
• decrease in vascularity of the labyrinth
|
• slightly smaller size from E10.5 on
|
• increase in the number of giant trophoblast cells at E9.5
|
• spongiotrophoblast cells are reduced
|
• decrease in spongiotrophoblast layer at E9.5
|
• the labyrinthine trophoblast layer is thickened but the labyrinth is thinner
|
• delay in chorioallantoic branching
|
liver/biliary system
small liver
(
J:70667
)
• livers appear small at E12.5
|
• total cellularity of liver is reduced 10-fold at E12.5
• however, embryonic hematopoiesis appears normal
|
cardiovascular system
• the network of embryonic vessels and maternal sinuses in the placenta are poorly developed
• by E12.5, dilation of maternal and embryonic vessels and pooling of maternal blood in the labyrinthine layer of the placenta are observed
|
• decrease in vascularity of the labyrinth
