title: Notochordal histogenesis: preliminary report of ultrastructural observations in chick embryo.
abstract: Transverse, frontal and sagittal notochord sections of chick embryos at different developmental stages were ultrastructurally examined. The notochord tissue organization appears to be more likely to build a stiff but flexible body axis than to have an inducting role on the surrounding embryonic structures.
