WebJun 1, 2005 · The notochord is the defining structure of the chordates, and has essential roles in vertebrate development. It serves as a source of midline signals that pattern surrounding tissues and as a major skeletal element of the developing embryo. WebThe mesenchyme under the induced neural tissue appeared to be derived mainly, if not entirely, from the graft. The boundary between labelled and host mesodermal tissue was sharp. It is remarkable that in several cases a notochord attached to the induced neural tube is shown actually to be derived from the graft. how do you say transportation in spanish
