Flow cytometry of keratinocytes.

O P Clausen

    Journal of Cutaneous Pathology
    |February 1, 1983
    PubMed
    Summary

    Flow cytometry (FCM) enables rapid quantification of cellular components. Combining DNA FCM with cell kinetic methods offers new insights into keratinocyte proliferation and skin disease classification.

    Area of Science:

    • Dermatology
    • Cell Biology
    • Biotechnology

    Background:

    • Flow cytometry (FCM) requires isolated single cells for analysis.
    • Keratinocyte isolation procedures are established for both animal and human samples.
    • FCM offers accurate and rapid quantification of cellular constituents.

    Purpose of the Study:

    • To explore the application of FCM in keratinocyte research.
    • To investigate DNA content analysis for cell-cycle and ploidy studies in keratinocytes.
    • To evaluate the combined use of FCM and cell kinetic methods for understanding keratinocyte proliferation.

    Main Methods:

    • Isolation of single keratinocytes from animal and human tissues.
    • Flow cytometry (FCM) for DNA content analysis and cell-cycle distribution estimation.
    • Integration of FCM data with other cell kinetic measurements.

    Main Results:

    • FCM successfully quantified cellular constituents in keratinocyte suspensions.
    • DNA FCM provided insights into cell-cycle distributions and ploidy in mouse epidermis.
    • Combined methods yielded novel information on epidermal cell-cycle progression.
    • DNA FCM showed potential in classifying healthy and diseased human epidermis.

    Conclusions:

    • Combined DNA FCM and cell kinetic methods are optimal for studying keratinocyte proliferation.
    • DNA FCM can aid in the classification of specific skin diseases.
    • Future research should explore parameters beyond DNA content for keratinocyte characterization.
