  • Title: Somite formation in the early chick embryo following grafts of Hensen's node.
    Author: Hornbruch A, Summerbell D, Wolpert L.
    Journal: J Embryol Exp Morphol; 1979 Jun; 51():51-62. PubMed ID: 479748.
    Abstract:
    Quail grafts of Hensen's node were examined for their potential to induce somites in chick blastoderms. The origin of the structures induced depended on the distance of the graft from the host's midline. Nodes placed at the margin of the area pellucida resulted in structures differentiated from the cells of the graft, whereas medially the graft organized host cells to form rows of somites. The results are discussed in terms of competence of graft and host mesenchyme and a positional signal from the node.
