    Area of Science:

    • Cell Biology
    • Biotechnology
    • Biophysics

    Background:

    • Flow cytometry is a key technique for analyzing cell populations.
    • Understanding cell cycle kinetics is crucial for cancer research and drug development.
    • Traditional methods for cell proliferation studies have limitations.

    Purpose of the Study:

    • To review the utility of flow cytometry in cell proliferation studies.
    • To detail a novel technique for simultaneous DNA content and bromodeoxyuridine measurement.
    • To explore applications in cell cycle phase determination and drug resistance detection.

    Main Methods:

    • Univariate DNA distribution analysis for cell cycle studies.
    • Simultaneous flow cytometry for DNA content and bromodeoxyuridine incorporation.
    • Cytochemistry for specific cellular labeling and analysis.

    Main Results:

    • Accurate determination of cell cycle phases (G1, S, G2+M).
    • Quantification of cell cycle phase durations and dispersions.
    • Detection of low-frequency drug-resistant cells.
    • Analysis of tumor response to cell cycle-specific agents in vivo.

    Conclusions:

    • The reviewed flow cytometry techniques provide robust methods for cell proliferation analysis.
    • Simultaneous DNA and bromodeoxyuridine measurement enhances cell cycle kinetic studies.
    • This approach is valuable for fundamental research and preclinical drug evaluation.
