  • Title: [Centrioles in the cell cycle of L cells].
    Author: Vorob'ev IA, Chentsov IuS.
    Journal: Ontogenez; 1987; 18(5):478-83. PubMed ID: 3696675.
    Abstract:
    The structure of centrosome in non-synchronous L-cells culture during the cell cycle has been studied. In mitosis, mother and daughter centrioles, which differ in their ultrastructure, are located perpendicularly in the pole of the spindle. Microtubules, meeting in the pole area terminate mainly in electron-dense clottings of fibrillar matter surrounding the diplosoma. In telophase, disjunction of mother and daughter centrioles begins. At the beginning of G1-period, centrioles move off from each other for several micron, and then draw together again without forming diplosome. Pericentriolar satellites form on mother centriole of some cells at this time, they disappear at the beginning of S-period, replication of centrioles begins; daughter centrioles reach the size of mother centrioles in anaphase. During growth and maturation, centrioles in L-cells undergo structural changes similar to those described for SPEV cells (Vorob'ev, Chentsov, 1982). Several types of meeting points for microtubules exist in L-cells during the whole interphase: surface of centrioles per se, pericentriolar satellites, free foci.
