An axoneme develops on one of the centrioles (figs 2 and 20b), whereas the other remains oriented in a cytoplasmic bud and later aborts. Striated filamentous bundles associated with centrioles in pulmonary lymphatic endothelial cells. In some types of cultured mammalian cells one of the centrioles, the maternal centriole, often develops a rudimentary cilium during interphase. A fibrous body with a striated appearance lies lateral to the centrioles. The cilia emanate from one of the basal bodies, which are derived from the centrioles. There are two kinds of centrosomes: centrosomes containing a pair of centrioles and acentriolar centrosomes. Lateral to the centrioles there is a fibrous body with a striated appearance in longitudinal section. The two remaining centrioles are situated on either side of the central body and each forms a basal body. They multiply producing two new centrioles at a short distance from the old ones.

Two centrioles appear within the protrusion; at first, they are formed on both sides of the nucleus (fig. 2c) and then at right angles to each other. We did not find centrioles at the spindle poles and, to our knowledge, no one has observed centrioles at the poles of the first mitotic spindle in the rabbit. For example, both species have lost one of the centrin subfamilies that are usually associated with centriole duplication.
