本文用相镜、光镜和电镜研究了胚胎兔脊神经节成神经细胞从神经嵴迁移到单极神经元的分化过程。相对未分化的迁移神经母细胞，它有单一的原始神经突，含有细丝和大量的核糖核蛋白颗粒，但很少膜内质网。在高尔基-中心粒区域存在大量的神经管，可能起源于中心粒，是神经母细胞进一步成熟的最初迹象之一。神经管迁移到神经突中，在那里它们成为发育过程中的突出特征，特别是在远端突起中。
The differentiation of the neuroblast of the spinal ganglion of the embryonic rabbit has been studied by phase, light, and electron microscopy from the period of migration of the cells from the neural crest until their transformation into unipolar neurons. The relatively undifferentiated migratory neuroblast, which has single primitive neurite, contains fine filaments and large numbers of ribonucleoprotein particles, but very little membranous endoplasmic reticulum. The presence in the Golgi‐centriolar region of large numbers of neurotubules, which probably originate from the centriole, is one of the first signs of further maturation of the neuroblast. The neurotubles migrate into the neurite, where they become a prominent feature during development, particularly in the distal processes.
