Abstract
Structures consisting of connecting rings surrounding a fibrillar core were observed within nucleoli of developing normal and axotomized hamster facial motoneurons. A few appeared in the nucleoplasm, attached to coiled bodies. Their peculiar structure and temporal association with neuronal maturation may reflect a transient state of ribosomal RNA transcription.
摘要
在发育中的正常和轴突切断的仓鼠面部运动神经元的核仁内，观察到由围绕纤维状核心的连接环组成的结构。少数出现在核质中，附着于卷曲小体。它们独特的结构以及与神经元成熟的时间关联可能反映了核糖体RNA转录的一种短暂状态。
