|
• 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

|
|
• much smaller than littermates; length of embryo in yolk sac is ~50% of control embryo length
