Centrioles are microtubule-based organelles that are embedded within pericentriolar material (PCM). Together, they comprise the centrosome, a microtubule-organizing center. PCM can sometimes exist in the absence of centrioles, but a new example of acentriolar PCM in neurons offers deeper insight into the relationship between these two entities.
中心体是微管为基础的细胞器,嵌入在中心粒周围物质(PCM)中。它们共同构成了中心体,一个微管组织中心。PCM 有时可以在没有中心体的情况下存在,但神经元中无中心体的 PCM 的新例子为这两个实体之间的关系提供了更深入的了解。
