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.
对亨森结的鹌鹑移植体进行了检测，以研究其在鸡胚盘诱导体节形成的潜力。所诱导结构的起源取决于移植体与宿主中线的距离。置于透明区边缘的结导致结构由移植体细胞分化形成，而在内侧，移植体组织宿主细胞形成体节排。根据移植体和宿主间充质的感受态以及来自结的位置信号对结果进行了讨论。
