nervous system
|
• the DiI-labeled cells do not respond to Sema3F in cultured telencephalic slices prepared from E10.5 embryos
• migration stream is not biased to either the distal or the proximal side of the Sema3F aggregates, but directed ventrally in cultured telencephalic slices prepared from E10.5 embryos
• increased number of lot cells spread over the deep medial region at E12.5 and E13.5
|
|
• normal surface distribution of lateral olfactory tract cells
• normal total numbers of lateral olfactory tract cells
• about twice as many lateral olfactory tract cells are ectopically distributed over the deep layers at the restricted rostrocaudal middle level at E12.5 and E13.5

|
mortality/aging
|
• embryos die at E10-10.5, showing longer survival thah double homozygous embryos
|
embryo
|
• yolk sacs are of normal size, but lack larger collecting vessels and contain irregular and less dense capillary networks
• vasulature of yolk sac at E10 is characterized by vessel heterogeneity, disorganization, and immaturity
• arterial and venous branching is not seen in yolk sacs at E10
• thickened blood vessels, lack of capillaries, and large avascular spaces between blood vessels are observed, with occasional dead-ended sprouts not connected to other sprouts
|
|
• much smaller than littermates; length of embryo in yolk sac is ~50% of control embryo length
|
growth/size/body
|
• much smaller than littermates; length of embryo in yolk sac is ~50% of control embryo length
|
cardiovascular system
|
• avascular regions, vessel size heterogeneity, and thickened blood vessels are observed
• outflow tract formation is abnormal
• blood vessel density in head region is slightly higher than in Npr1tm1Hfu/Npr1+; Npr2tm1Mkl /Npr2tm1Mkl embryos
|
|
• abnormal formation of dorsal aorta is observed
|
|
• yolk sacs are of normal size, but lack larger collecting vessels and contain irregular and less dense capillary networks
• vasulature of yolk sac at E10 is characterized by vessel heterogeneity, disorganization, and immaturity
• arterial and venous branching is not seen in yolk sacs at E10
• thickened blood vessels, lack of capillaries, and large avascular spaces between blood vessels are observed, with occasional dead-ended sprouts not connected to other sprouts
|
|
• multiple hemorrhages are observed in embryos at E10
|

cardiovascular system
