when neural crest cells were grafted to a ventral position , between the notochord and dorsal aorta , in this intersomitic pathway at the axial level of the last somite , the grafted cells migrate rapidly within 2 hr in two directions : ( 1 ) dorsally , in the intersomitic space , until the grafted cells contact the ventrally moving stream of the host neural crest and ( 2 ) laterally , along the dorsal aorta and endoderm .
