Figs. 307 & 308 from Don Fawcett's Chapter 12 (Centrioles). In interphase cells, microtubules commonly radiate from the centrosome, and in dividing cells the microtubules of the mitotic spindle conver...

Four centrioles imaged in one electron micrograph of a thin section, cut from a Chinese hamster fibroblast grown in tissue culture. The two centrioles that appear circular are the 'mother' centrioles,...

Figure 302 from Chapter 12 (Centrioles) by Don Fawcett. The centrioles replicate early in cell division and take up positions at either pole of the division figure. Concurrently with the condensation ...

Figs. 309 & 310 from Don Fawcett's Chapter 12 (Centrioles). The plane of a thin section only rarely happens to coincide with the long axis of both members of a pair of centrioles. It is more common fo...

An electron micrograph showing that a centriole is constructed from a ring of nine triplet microtubules. Most animal cells contain two to four centrioles. In longitudinal view, a centriole looks like ...

Centrioles multiply exactly once in preparation for cell division.In this remarkably rare image, four centrioles are seen in one electron micrograph of a thin section cut from a Chinese hamster fibrob...
