摘要用鹌鹑-雏鸡标记技术及光镜和电子显微镜研究了覆盖神经系统和皮肤感受器的细胞的起源。在第一个实验系列中，将10~14个HH阶段的鸡胚的相应神经管片段移植到鹌鹑的臂部神经管中；在第二个系列中，将18~20个HH阶段的鸡胚的腿芽移植到相同阶段的鸡胚中，反之亦然。结果发现，脊髓的所有脑膜层、周围神经的神经膜和神经内膜，以及Herbst感觉小体的包膜和内腔细胞都是由局部间充质细胞发育而来的。雪旺细胞和感觉小体内核的细胞起源于神经脊。默克尔细胞的前体细胞类似于雪旺细胞迁移到肢芽中，在那里它们随后分化。这意味着，除了雪旺细胞和黑素细胞外，还有更多源自神经脊的细胞亚群进入肢体。
SummaryThe origin of cells covering the nervous system and the cutaneous receptors was studied using the quail-chick marking technique and light and electron microscopy. In the first experimental series the brachial neural tube of the quail was grafted in place of a corresponding neural tube segment of the chick embryo at HH-stages 10 to 14. In the second series the leg bud of quail embryos at HH-stages 18–20 was grafted in place of the leg bud of the chick embryos of the same stages and vice versa. It was found that all meningeal layers of the spinal cord, the perineurium and the endoneurium of peripheral nerves, as well as the capsular and inner space cells of Herbst sensory corpuscles, develop from the local mesenchymal cells. Schwann cells and cells of the inner core of sensory corpuscles are of neural crest origin. The precursors of Merkel cells migrate similarly to the Schwann cells into the limb bud where they later differentiate. This means that in addition to the Schwann cells and the melanocytes a further neural crest-derived subpopulation of cells enters the limb.
