There is some discussion as to whether these cells contributed from the notochord are replaced by others from the adjacent mesoderm. It gives rise to the [[notochordal process]] which later becomes the [[notochord]] ==External links== * [http://instruct1.cit.cornell.edu/courses/biog105/pages/demos/106/unit03/17d.notochorddev.html Diagrams at cornell.edu] {{developmental-biology-stub}} {{Gray's}} {{Embryology}}[[Category:Embryology]] [[Category:Developmental biology]]
