mortality/aging

embryo
• lack of invaginating blood vessels into the trophoblast layer and absence of branching morphogenesis of the vessels
• networks generated by the allantois are smaller and less complex
• unevenly sized vessel lumens, some of which are large, giving an impression of accumulations of endothelial cells
• yolk sacs display large open spaces which are lined by endothelial cells
• defect in labyrinth formation
• defect in labyrinth formation
• wrinkled yolk sac at E10.5
• blood cells appear to accumulate in a few places
• however, no defect in embryonic hematopoiesis is detected
• the primary vascular plexus fails to remodel

cardiovascular system
• the capillary network is replaced with a large accumulation of endothelial cells
• no capillary sprouting from the perineural plexus toward the midline is observed in hindbrains
• lack of invaginating blood vessels into the trophoblast layer and absence of branching morphogenesis of the vessels
• networks generated by the allantois are smaller and less complex
• defect in vascular maturation and remodeling, especially apparent in the midbrain
• vascular networks formed in cultures of para-aortic splanchnopleural region explants
• from E8.5 embryos are not as complex with fewer but thicker branches and contain characteristic endothelial cell accumulations
• decreased branching indices in networks formed by allantois explants
• no capillary sprouting from the perineural plexus toward the midline is observed in hindbrains
• at E10.5 in the region below the otic vesicle no new sprouts are detected and the neck region contains fewer, thicker vessels
• unevenly sized vessel lumens, some of which are large, giving an impression of accumulations of endothelial cells
• yolk sacs display large open spaces which are lined by endothelial cells

integument
• at E10.5

nervous system
• the capillary network is replaced with a large accumulation of endothelial cells
• no capillary sprouting from the perineural plexus toward the midline is observed in hindbrains

cardiovascular system
• the complexity of the network formed is reduced in E10.5 hindbrains with shorter vessels, incompletely formed interconnections and fewer branching points
• however, by E11.5 these differences are no longer apparent
• slight delay in vascularization seen at E10.5 but no longer detected at E11.5
