Notochordal histogenesis: preliminary report of ultrastructural observations in chick embryo.
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.
