Figure 301 from Chapter 12 (Centrioles) of 'The Cell' by Don W. Fawcett M.D. Centrioles are usually positioned so that their long axes form a right angle. Their perpendicular orientation is maintained even though they may be half a micrometer or more apart and have no visible structural elements connecting them. The nature of the long-range forces or organization of the centrosomal cytoplasm that are responsible for this relationship are unknown. Departures from the usual orthogonal arrangement are occasionally encountered in normal cells and are reported to be common in malignant tumors. A copy of the chapter is available on the ASCB's BioEDUCATE website.

图301摘自《细胞》第12章（中心体）由Don W. Fawcett M.D.所著。中心体通常以使其长轴形成直角的方式定位。尽管它们可能相隔半微米或更多，且没有任何可见的结构元素将它们连接，但它们的垂直取向仍得以维持。负责维持这种关系的长程力或中心体胞浆的组织性质尚不明确。在正常细胞中偶尔会遇到偏离常规的直角排列，且据报道在恶性肿瘤中此类排列较为常见。该章节的副本可在ASCB的BioEDUCATE网站上获取。
