    Notes: HeLa S3 cells in suspension culture are resynchronized in each successive generation by exposure to 0.25mM thymidine. The resynchronization approach appears to be superior to single- and double-block techniques because the period of effective inhibition of DNA synthesis is significantly shortened. Gram quantities of highly synchronous viable cells have been produced on a daily basis.

    Maintenance of perpetual synchrony in HeLa suspension cultures: Question of unbalanced growth (1975)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Unbalanced growth has been studied in HeLa cell cultures maintained in perpetual division synchrony by periodic inhibition of DNA synthesis. Observation of eight independent cellular parameters indicates that once synchrony has been established the degree of unbalanced growth in later cycles is not as great as is observed with the conventional “double-block” technique. This significant diminution of unbalanced growth appears to be related to the significantly shorter periods of inhibition of DNA synthesis used in the resynchronization process.

    Behavior of subcellular marker enzymes during the Hela cell cycle (1975)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 17 (1975), S. 695-701

    Notes: Six enzymes associated with the activities of the nucleus (thymidine kinase), mitochondria (succinate dehydrogenase), lysosomes (acid phosphatase), peroxisomes (catalase), (cytosol lactate dehydrogenase), and the intermembranal mitochondrial space (alkaline DNase) were assayed at 2 hr intervals over the division cycle of repetitively resynchronized HeLa cells. The results indicated a high degree of reproductibility for cells synchronized by the method of perpetual resynchronization and may be of direct use to those interested in subcellular organellogenesis.
