In the spinal ganglia of the rabbit the nerve cell bodies, which in early developmental stages are mutually in contact, come to be completely isolated from each other by a satellite cell sheath and by a connective envelope before birth. The present study demonstrates that in the early postnatal months some nerve cell bodies are still arranged in clusters, and that the percentage of these decreases progressively throughout adult life. This decrease probably arises because in some of the ganglion neurons the process of envelopment of the perikaryon by an individual sheath begins later, or takes place more slowly, than in the majority of cases. Therefore, the relationship between neurons and between neurons and satellite cells may change in certain clusters of nerve cell bodies under normal circumstances during adult life.
在兔的脊髓神经节中，神经细胞体在发育早期相互接触，在出生前通过卫星细胞鞘和结缔组织包膜彼此完全隔离。本研究表明，在出生后的最初几个月里，一些神经细胞体仍成簇排列，并且在整个成年期，这些成簇排列的神经细胞体的百分比逐渐下降。这种下降可能是因为在某些神经节神经元中，单个鞘对核周体的包裹过程比大多数情况开始得晚，或者发生得更慢。因此，在成年期正常情况下，某些神经细胞体簇中神经元之间以及神经元与卫星细胞之间的关系可能会发生变化。
